i think you accident a word but do you mean it worked on older phones?
things you can do:
1. The Amaze and SGS2 requires "new" sim cards for wifi calling (the sim that came with the phone) so use that sim instead
2. Go to a T-mobile store and ask for the new SIM. (free-$20 different stores different policies)
3. Call T-mobile to help you "activate and setup" your wifi calling in your ACCOUNT, not on the phone.
4. Call CS and ask them to issue you a new sim card (they either send you to a store or mail you one)
5. Use the search button because I remember reading about this a couple days ago.

If you go to an actual tmobile store and not a dealer and tell them that you called tmobile and you were told the sim would be FREE, they won't charge you for it. But make sure you test wifi calling at the store before leaving the store, so you don't have to drive back to the store like I had to.

" Your SIM card does not allow a connection to this network "

Hi there,
I'm on vaca for one month in Africa and I am trying to use my sim card but I have this message :" Your SIM card does not allow a connection to this network "
I tried two different sim cards but I still have the same issue.
Note that the phone was working perfectly yesterday with my Tmobile Sim Card.
It's an international One X so I don't think that I need to unlock it.
Do you guys have any solutions?
Thank you

it sounds like something tmobile end has changed on your account, if possible i'd call them to see if they can help get it working again
other thing to check is the roaming settings, check its enabled etc

Thanks for the reply.
I'm not using that Tmobile sim card anymore. But an Orange one.
Should I factory reset it and see if it'll work?
Thanks

i had this happen on mine, ive got tmobile sim, it went to tmobile orange signal, i tried to manually switch it back to tmobile (better signal coverage) and it said the same thing.
A reboot didnt fix it so i went into settings, storage, make more storage and then cleared all temporary data for all apps.
this seems to temp fix the issue and allows me to reconnect to my peferred network it still happens every now and then so it could be a software gitch with the hox

Just tried it. Didn't work
I will restore it and see how it goes

Even with the New Rom, Superwipe I still have the same issue ?

need help figuring this out with my sim

i have the gt-i9250 and i always used an at&t sim with it with out an issue, recently i wanted to switch to t-mobile (thinking the phone should be unlocked considering it was an international phone and was the yakjuxw than i flashed it to yakju which was wierd cause i had google wallet on it and it was working fine although i only thought it was compatible with takju, but anyway all and all i put it to the usa firmware of takju 4.0.4 not going to jellybean yet, but my issue is that i am not able to use the t-mobile sim card in it and i get this (look at screenshot where signal is) what does this mean and how come i cant get signal, when i go to settings and mobile networks it shows me the apn for t-mobile us but not selected so i select it than after i go to mobile networks and it shows t-mobile and at&t and when i click any of them they tell me its unable to connect and it cant connect to the network at this time, so what would this mean and how would i fix it so that i can use it with my t-mobile sim card, also i flashed the newer NA radio uglc1.

That is weird. It should work on either of them. It just means you have no signal. That is strange. You could've actually just popped the Sim right in. It didn't matter if you were using a ROM
Sent from my Galaxy Nexus using xda app-developers app

Is the SIM activated for sure? I know when I switched to the T-mobile $30 plan it took it a good 15 minutes or so to activate, and then I didn't actually get signal until rebooting the phone for whatever reason.

Did you reboot your phone?
Although you can sometimes hot plug a sim card by turning on flight mode, taking the sim card out and toggling flight mode a few times, it won't work sometimes.

probably your cell imei not free and therefore can not change your sim.
There is an application called "****docomo" worth to release the imei. Make a backup just in case

Don't think he has a SIM unlock problem. Considering that it was working with AT&T, which never had a locked version of the GNex, I think he's having another issue.
I'd tell the OP to make 100% sure that his new T-Mobile SIM is activated and not defective, then try a few reboots and swaps back to the old SIM and do some troubleshooting. If it's the phone and not the SIM, its likely a mobile network registration error or an APN issue.
Looking in the notification bar, it seems like the phone doesn't think there's even a SIM inserted. Make sure you didn't damage a pin in the SIM tray, and that the SIM is properly inserted and clean. I don't think you'd get this error of "no SIM" if your phone was locked. If that was the case, the phone would recognize the SIM and prompt for an unlock code, which you're not getting.

[Q] Just bought a used T-Mobile Note 10.1 2014

As the title says, I've been dying to get a Note 10.1. I finally got one but it happens to be a T-Mobile version and the sim card has been removed. I don't plan on getting 4G service ever if I can avoid it.
So now I have a few questions:
1. Will I be able to get updates like the wifi only tablets do or will I be forced to get T-Mobile service when updates come out?
2. I have these annoying notifications about the missing sim card. Is there a way around this? I have Sprint service for my phones so I really don't know much about sim cards. Do I need to go to T-Mobile and just ask for one to pop in without getting service? Are they free or would they send me packing because I don't have their service?
3. I also have the x'd out signal meter that I would love to get rid of.
Any advice you guys can give me as a sim card/carrier tablet noob would be very helpful.

- You can get updates with WiFi only in fact some updates requires a WiFi connection in order to download since all data plans are limited on tablets

- You can get a SIM card for about $10, however you don't need to have service with T-Mobile you can put the SIM card and whenever you are not connected to WiFi but you get LTE service it would send you to a page where you can add a data package but thats completely optional
I also have the x'd out signal meter that I would love to get rid of.

Once you put a SIM card it would go away maybe there is a Xposed module that can remove the signal meter and the No SIM card notifcation

Thank you very much. Good info.

Why not root and flash a rom that doesn't have those things enabled.
Flashing a wifi version of a rom might do the trick.
I've done the reverse and flashed a 4G rom to my Wifi only device and simpy disable the phone and sms apps. Sometimes you have to be careful but I haven't had an issue both ways.

[Q] Enable Mobile Hotspot on Unlocked ATT Galaxy Note 2

We have a Galaxy Note 2 from ATT now. Just upgraded, so we're not using it. We want to take it to Europe to use as a phone and a hotspot for our computers on our trip. I've read that people do that with unlocked Androids and a European SIM.
I was able to unlock the phone with no problem using a data only T-Mobile SIM card in the process. The problem is that I can't turn the Mobile Hot Spot on. I've tried with the valid data only T-mobild SIM installed. When I try to turn the hotspot on, it says that either the network is not available, or there's an invalid SIM. I'm worried that it's the ATT restrictions on the phone that aren't going away even if the phone is unlocked, and there's a different SIM in place.
Does anyone know what we have to do to enable the hotspot, so that this phone can be used in Europe?
Thanks.

Try with wifix.apk

Thanks. That looks like a good app to fix problems connecting to external wifi sources. However, I want my phone to BE the wifi source when in Europe. Still looking for a solution.

The thing that sticks out to me is that you actually need the correct Sim card that is provisioned for phone service.. I'm assuming this "data only sim" was provisioned for a tablet and therefore can't make any calls... the network unavailable message will show up even with no Sim installed and trying to enable a hotspot. You need a valid cell service in order to hotspot.

Hope Getting the Right SIM will do it.

Thanks. I hope that's what the problem is. It would make things simpler to be sure. I just didn't want to get there and then find out it wasn't going to work. In the meantime, I found my old Galaxy S 3. I managed to unlock it, root it, and install basic ROM. Thought maybe that would work, as well. I'll know by next week.
