Hi,
Just got my Cosmo the other day.
Need to get a nano SIM card for it.
My current cellphone has a larger SIM card.
Plan to go to AT&T store Friday to get one.
Hope all will work well with SIM card.
Anyone else use AT&T with Cosmo?
If so, works well?
Thanks,
Mark

Does this help?

Well, that's one way to get a nano SIM.....Thanks for the reference.
I will keep this in mind in case I have a problem getting one at AT&T store today.....
Question is if anyone has successfully gotten their Cosmo working on AT&T network or if any issues with doing that....
Thanks.
-
Mine is on att. No problems so far, but I am not heavy user neither with phone nor with data
-
I'm also using Cosmo on AT&T without any issues. Calls and texts work fine (no dropped calls or delayed messages).
-
Thanks, everyone, that has replied....
Meanwhile, I went to an AT&T Store.
Sales rep there was very helpful and intrigued by the Cosmo....was surprised (in a good way...) seeing the keyboard when Cosmo was opened up....
Got nano SIM.....and she helped get it setup...
Good news.....was able to receive a call.....
Bad news......
Phone only shows 3G on display, even though we checked settings and 4G is selected....
Also, couldn't get online with cellular connection....
I had to get back to work, so I was told to call AT&T tech support....will try to do that soon....
Any ideas as to what's wrong?
Thanks.

For data you need to setup APN - access point name. The instructions should be provided to you by your sim card seller. Here is the link to discussion of the process. (https://www.androidcentral.com/what-apn-and-how-do-i-change-it)

Thank you for your help...
Sales rep at store checked that too....said it looked OK to her.....but I wonder if something in the list of items is not set correctly?
A lot of items are 'Not Set' or 'Unspecified'.
Here's what I see:
APN Name: ATT Nextgenphone
APN: nxtgenphone
Proxy: Not set
Port: Not set
Username: Not set
Server: not set
MMSC: http://mmsc.mobile.att.net (http://mmsc.mobile.att.net)
MMS proxy: proxy.mobile.att.net
MMS port: 80
MCC: 310
MNC: 410
Authentication Type: Not set
APN type: default.mms.supl.fota
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6
APN enable/disable: APN enabled
Bearer: Unspecified
MVNO Type: None
NVNO Value: Not set
UPDATE Checked AT&T website. Looks like the APN settings shown below are for tablets, not smartphone. Is this OK?
Only real difference is for the line 'APN type'. For smartphones it shows: 'default.mms.supl.hipri'.
Thanks.

You might need to turn the cosmo off and back on after changing these settings
-
Thanks, have tried that several times.....
On phone with AT&T now.....
Lady is nice, trying to be helpful...
But struggling to figure this out....
-
Are your settings the same?
-
Now on phone with a higher level tech support guy....
He's tried a few things on his end....but no luck so far....
Now, he set up a ticket for engineering to assist....may take 24 - 48 hours he said....
Oh well, hope they get this sorted out....
Just my luck....

Thanks for sharing!
Interesting, your APN Type line info is different than what AT&T shows for smartphones and tables....
Forgot to mention that when I was on my office phone with AT&T, the Cosmo was getting no cell reception. My work cellphone with AT&T was getting 4 bars....so, that's strange....
Got home and turned on Cosmo and I get 3G and 2 bars.........but still can't get online with mobile data.....
This seems very strange to me.....
-
For several odd features you need to go settings and toggle that specific odd feature related setting and switch status or toggle on/off. And for example for Mobile data, you need swap it once between sim2 and sim1 before it really knows where...
Hope this help, I haven't yet received mine, but have read several odd features solved like this at startup of device.

Have toggled a few things in settings, but not all.....and restarted....can try doing some more....
Haven't tried swapping the sim1 and sim2.....can try that....
Thanks for your suggestions!

Swapped sim slots, then tried getting online....no go....
Swapped card back into sim slot 1, tried again, no go....
Also, toggled some of the settings each time.....

I do believe they are talking about in settings: Set SIM 1 for data, then 2, then back again etc...
(Your last sentence indicates you might have done that as well, but in case you didn't....)

Not sure where you're at, but check to see if ATT has 4G in your area ON A BAND THE COSMO SUPPORTS.

Good idea, Sath!....thanks.
I know there was 4G in the area where the AT&T store I went is located.
However, I did not check the band issue....had assumed PC had checked what bands AT&T uses, when designing the Cosmo...
So, will check this....
But still don't understand why mobile data does not work.....
-
This is the reply I received from PC regarding No 4G and No Mobile Data........
[size=]
The Cosmo is fully compatible with the AT&T 4G bands. Could you please navigate to Settings - Network & Internal - SIM cards and ensure that the AT&T SIM slot is the preferable SIM for mobile data? In some cases, as the Cosmo as 2 SIM slots, it will pick the empty one as a source of the mobile data.
Feel free to let us know if there's anything else we can help you with.
Kind regards,

Current AT&T US Bands:
1, 2, 3, 4, 5, 7, 8, 12, 17, 19, 20, 25, 41, 66, 71
Bands Cosmo supports:
2, 4, 5, 12, 14, 17, 29, 30, 66
So no, it doesn't support all ATT bands, but it does seem to support the main ones ATT uses, like 2, 4, 5, 12 and 17.
-
Thank you, Sath, for the detailed info.
Now if I can just get 4G and Mobile Data working, I will be all set.....
-
Just an idea -- since there is a possibility that cosmo get confused by sim slots, maybe you can straighten thing by putting in sd card to occupy the other slot. At least that is what i have and it is working for me.

Thanks for the suggestion, vldmr......
I put in a microSD in the other slot....
Makes no difference...
Still no 4G and no mobile data....
Also, regarding reception in my office at work.....
My work cell (iPhone XR) gets 3 - 4 bars inside my office (it has a window to the outside).
The Cosmo is mostly getting No Reception or occasionally gets 1 -2 bars......
This is all NOT Good......
-
You know, looks like you just have hardware problem - like antenna is not connected properly. That would explain everything. Just press on with PC support.

Thanks again for your help.
That's what I started to suspect.....just my luck.....
I responded to their non-helpful reply yesterday, asking for specific ways to resolve my problems. Have not receive a response to that request as of now.
But I did say if they don't help me get Cosmo working, I will ship it back for a refund.
Oh well.....
-
Got another 'helpful' email from PC support:
[size=]Dear Mark,
Thanks for your reply.
Could you please navigate to Settings - Network & Internet - Mobile network and take screenshots for us of the full window? I wonder if "Mobile data" is set to on as well, that has to be on.
The Cosmo fully supports the T-Mobile network bands, so there couldn't be a hardware limitation about this. It sounds like a software setting.
Feel free to let us know if there's anything else we can help you with.
Kind regards,
Customer Care Team[/size]
I replied stating one more time all the things I've done to try and get this working and asked (one more time...) how they can explain why my work iPhone gets 3 -4 bars in my office and Cosmo gets NO reception. Then said this must a hardware issue, not a software issue, and that I want to send back the Cosmo.......
-
Did you try to pop sim card from your work iphone into cosmo?
-
Did you try to pop sim card from your work iphone into cosmo?
Great idea!
Just tried this and voila!
Get 4 bars and VLTE 4G shown!!!!
And Mobile Data works!!!
You're a genius, vldmr!
Good thing I didn't ship my Cosmo to UK yet....
So, assume this means I received a bum SIM card from AT&T?
UPDATE
Compared the numbers on both cards....
Think the AT&T store person gave me a 3G card.....
It has a number 3026 on the card.
My work phone has a number 4026 on the card.
I'm guessing the 4 means 4G and 3 means 3G......
-
UPDATE
Just returned from trip to local AT&T store....
Guy at this store was great and very helpful.
Turns out issue is not about the SIM card.....it's all about the IMEI number used.
Unfortunately, since PC does not have AT&T sell their phones, they don't have an IMEI number that identifies the device as a Cosmo. Therefore, the system doesn't know to provide it with 4G and mobile data.
After trying all the possible APN's available and not getting 4G, he entered an IMEI from an iPhone and Voila! the Cosmo got 4G and mobile data instantly.
So, for those of you that got your Cosmo's working without all the headaches I went through, the AT&T guy said there were two options.
One, you transferred an existing SIM card from a phone that is recognized in AT&T system / IMEI.
Or if you went to AT&T store and got new SIM, the person helping you did what my guy did and didn't tell you.
AT&T guy said that I need to see if it still shows 4G after about 36 hours from now, as he said their system does a periodic sweep of devices on system. He thought there might be a small chance that system might detect that IMEI is for iPhone while device is not an iPhone. If that happens, it would likely downgrade Cosmo back to 3G. And if that happens, he said to come back to store or call AT&T to reset it again.
So it goes......but at least I now have 4G and mobile data......
Thanks to all who helped. Really made a big difference!

That is correct - my sim card was transferred to cosmo from at&t branded phone

Lucky you......
I figure between 2 visits to AT&T store, call with AT&T tech support, OESF posts, my fiddling around with Cosmo, I probably wasted about 6 - 8 hours on getting phone working right......
Oh well......
I do feel a lot better about the Cosmo now though....
Now need to spend some time learning all the features that are different from the Gemini I have.....
-
Glad you got to the bottom of this.

Thanks, Jake, yeah, me too......
Just wish it didn't take so much of my time and energy.....
Oh well, live and learn, they say....

The guy at my local AT&T store did the same for my Cosmo but he registered the SIM with a Samsung Note 8. It worked great until today when AT&T's system did a sweep and booted my phone off. I can't be going through this game every month. Not sure what to do now.
UPDATE:
So over lunch I walked around downtown and it seems I have VoLTE and 4G there so it may be that there is something wrong with the tower near my home. The odd thing is that it drops down to 3G near my office which it didn't do before today either. In my account, it also says "Unknown Unknown" for the device which is what it said when I had trouble getting it on AT&T's system when I first got the phone. I guess I'll see what happens tonight when I get home from work. Hopefully it is a problem with just the tower near my home and the rest is just coincidental.

Hi VAMM,
Maybe I'm just lucky, but I not gotten booted off...
My AT&T guy, entered info as if it's an iPhone....don't know if that would make a difference.
My guy said if I did get booted off, to come back to store and he'd re-do it...he thought that would take care of it.
So, have store try it again and see what happens....
Good luck,
Mark
-
This seems monumentally stupid to me. The whole *point* of the SIM card -- the Subscriber Identity Module, after all -- was to enable users to pick networks and handsets independently. You're saying that you can't (reliably) do that in the US?

Thanks for the response. I'm starting to suspect (and am hopeful) that the issue is just the tower near my house.
However, if it is more than that, I'll give the iPhone trick a try if someone at the store knows how to do it.
Cricket Cellular's system says the phone is compatible and AFAIK, ironically, Cricket is owned by AT&T. If I continue to have trouble, I may try getting a Cricket SIM to see how that goes.

It is indeed monumentally stupid. It appears that the only way to get the phone to work right on AT&Ts network is to fool the system into thinking it is a different phone. If you just give them the Cosmo's IMEI, they will say the phone is incompatible. The first time around, the person at the store was very helpful and stuck with it until he got it working but I was there at least two hours and even he was getting frustrated with AT&T's tech support. He had warned me after he got it working that AT&T may boot the phone off (actually, they just reduce the provisioning level down to uselessness).
-
Here's what AT&T guy told me.
The problem is related to fact that AT&T does not carry the Cosmo in their phone line-up.
Therefore, their system does not recognize it as a legitimate phone to be allowed on their network, ie, it's viewed as a potential security risk and thus booted off.
So, best you can do is to try and fool the system into thinking you are using an AT&T phone.
So far, it's working for me and it's been over two months now.

That's ludicrous.
I can walk into any random mobile phone shop / order off Amazon / eBay / Alibaba / whatnot and buy a handset, then buy a SIM card from any one of the networks by walking into one of their shops / online / over the phone, plug one into the other, and get on with my life. Which, AIUI, was what the GSMA was aiming for.
I'd complain if I were you, then change networks. Or are they all this bad?
-
Hang on, how does roaming work? I assume they do actually support foreign users?

Hang on, how does roaming work? I assume they do actually support foreign users?
Good question. I don't know for sure. Either you get a reduced level of service like 3G only or, if your phone happens to be a supported model, you get lucky with full service. This is just my theory though.
-
I'll add mobile networks to banking on the list of things the US is way, way behind the rest of the world on, then...
That's just perverse.

So, I came home from work and confirmed that I've been de-provisioned down to no data and 3G cellular which at my home means almost no signal. What a PITA.
Sorry to hear.....
Think it would be worth having AT&T change it to be like one of the new iPhones.
Have had no problems with Cosmo for over two months this way.
So, definitely worth a try.

I'll have to give it a try I guess but I just know it's going to be an ordeal.
UPDATE: It appears that T-Mobile at least recognizes the Cosmo's IMEI:
Good news!
You should have a great experience using your own phone with T-Mobile—it has features that typically perform well on our network.

The only bad thing for my situation is that a few years back T-Mobile had terrible signal strength around my house. I might try buying a pre-paid SIM from them and seeing if things have improved.

TMo has definately had a rocky history with signal strength, at least compared to
verizon in most places... But it seems like they keep adding new signal and
new "low frequency" support that's supposed to help things...

So far, things have been going better with my Cosmo then reception was with
my Gem.

Spent a couple hours wasting time with AT&T support on Friday. Got the "we'll call you back" (which they didn't) brush off so I went to the AT&T store for help. The guys there were sympathetic and did what they could but they had no luck restoring my service even after telling their system the Cosmo was a Samsung Note 10.
So, on Saturday I went to T-Mobile and got a prepaid plan just to test out the signal strength around my house which, the last time I tested it a few years ago was near zero. The guy at the store put in a SIM and their system recognized my phone with no problems. He mentioned that if signal was still an issue around my property that they would provide a free signal booster. I took the phone home to test the signal and fortuitously, signal strength in my house was quite good (actually about one bar better than AT&T). I went back to the T-Mobile store today and ported over my number. I don't think I was there for more than five minutes. In all, probably not more than twenty minutes with both visits combined. They couldn't have made it easier.
I never had trouble with AT&T's service until this phone issue. It's too bad they weren't really interested in or able to connect me to the people in the company that could provide a resolution.

That's too bad.....but glad you have service now.
All the AT&T guys needed to do was change setting to be same as iPhone. Don't know why they couldn't do that for you, it was easy for AT&T guy at my store.....Oh well.
Again, glad you have service now.

I told told him about the iPhone trick. He was walking from phone to phone on the display models to find an IMEI to use (I guess) and for whatever reason, landed on a Note 10. He did go through the iPhones but I think he figured he'd have better luck with another Android phone. I didn't want to press him on it because he was nice enough not to just brush me off. At that point I was already committed in my mind to trying T-Mobile.
