T-Mobile Sim No Signal(Other sims work) - Nexus 5 Q&A, Help & Troubleshooting

Recently revived my N5 that had been sitting around due to my N6P showing some water problems in case I needed to switch phones quickly.
Well, after resetting and installing AOSP Extended, I put my T-Mobile sim in, and gets no signal. It will recognize a sim is in, but I get no service at all. I figured something could be wrong with the simreader, so I tried some other sims. Sprint sim and a Freedompop(AT&T) sim both work. I know my T-Mobile sim works, as I'm currently using it in my 6p. Anyone have any solution?

freedompop uses at&t for GSM devices and sprint for CMDA devices. it sounds like your phone is the CMDA version, and your using the sprint network with freedompop. T-mobile is a GSM network and will not work with CMDA phones.

Adding Verizon to Network Operators?

I unlocked my MyTouch 4g (Glacier) and I want to use my Verizon sim card in it but it does not detect Verizon in the network operators. How do I get verizon on there? Is it possible? I thought unlocking it would allow me to do this.

Verizon does not use 'SIM' cards
as 'SIM' cards are used for GSM networks and Verizon is a CDMA provider

I did google this extensively. The phone that I have here is on the verizon network and has a sim card. Why would I make that up?

Verizon is a CDMA network. The SIM card is there because the phone you have also has a GSM radio for traveling overseas. However, just because it says "Verizon" on the SIM card doesn't mean your phone connects to Verizon when you roam. It's actually connecting to Vodafone when you're roaming in most countries. That's what the SIM card slot is for. Now if you unlocked that phone, you could use it on T-Mobile or AT&T if you set it to GSM Mode.
That Verizon phone will work in the US and Canada whether or not that SIM card is in there. It's impossible to get a GSM phone (your MyTouch 4G) to work on a CDMA network (Verizon).

Thank you for the real explanation and not being a jerk about it, as I did not know this.
It sucks that I cant use it but now I know.

[Q] Droid Maxx: Not activated on Verizon, won't work

After several long calls with Verizon and help from Motorola insiders, I have been given to understand that:
1. Droid Maxx if not activated on Verizon, before leaving US, cannot be used on other carriers (say in Europe or Asia).
The reason is the SIM unlock cannot be done by the customer support since they won't see the device in their network if it is not activated first.
2. The activation cannot happen outside US, since Verizon does not have a network.
So bottom line is get the device activated before you import it from US.
Now, my Droid Maxx is locked to Verizon. I know the boot loader can be unlocked. Will this help me in flashing something that can get rid of the SIM lock that Verizon has in place.
My device is an employee edition so perhaps there was some extra protection added there by Verizon.
Please help.
I do not have a Maxx, but I'm replying because you PM'd me asking to take a look at this thread..
It has been my experience that Verizon's 4GLte phones are sim unlocked (on the GSM side) out of the box. I thought that was a condition of VZW's 700Mhz spectrum auction win? One potential issue is does the phone support the needed bands out of the box (think Bionic where a hack was needed to enable bands needed for T-mobile).
That being said, if your Maxx is truly SIM LOCKED, then unlocking the bootloader wont help you SIM unlock, nor will flashing a 3rd party Rom after unlocking the bootloader.
where are you located, and who is your carrier? Do they use CDMA for voice, or GSM? What happens when you put a non-VZW sim in the phone?

Thanks Mark.
The phone Droid Maxx does support these bands since there are others who are using the same phone on GSM networks in the country.
The networks in India are:
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 2100
4G capabilities LTE 2300 (this one won't work with the phone, plus my carrier does not have it either)
The CDMA is CDMA 2000 - but I have not been able to try with a CDMA SIM, but that one has a higher probability of working.
When I put a non-VZ SIM, and set to Global mode, it does not detect any signal and the search network does pretty much nothing. The automatic mode tries to connect but then throws an error saying "can't connect to this network at this time"
I am using a brand new nano SIM card (which now is back in my Moto Defy with an adapter.)
Earlier I had a normal SIM converted to a nano SIM and that one did not work, but after I put in APN manually, I was able to access data.
I tried another user's cut-nano SIM and that one worked for data out of the box (another GSM provider).
Ditto for me, but I am using DroidMini... I also have DroidMAXX which is working great (even unlocked its BL and rooted it)...
I am also from India... Using it in GSM networks... I may get one Nano CDMA SIM to test later and will report here for sure...
Thanks...

Well, we have interacted on Rimweb recently.
The radio on the Droid series is the same. The difference between the mini and the maxx in your case is that the mini has never been activated on VZ network and hence it is SIM locked. Whereas, the Maxx would have been purchased as a used item (perhaps just activated and then sold off?). So that takes care of the SIM unlock part.
Yesterday I spend around 60 minutes with global support, VZ.
I escalated the issue to the supervisor.
He checked and said that the IMEI is clean and not in any sort of negative list. So there is nothing else that they can do.
He also said, the phones are unlocked by default for global use.
Obviously they don't want to dig deeper into why three phones are not working on GSM in India.
I am now running out of avenues. Does anyone have some debugging tool which can log what is happening when the phone tries to log on to the network?

The current Droid Maxx that Verizon sells supports the following..
LTE Band 13/4 700/1700
EDGE/GSM: 850/900/1800/1900,
HSPA/UMTS: 850/900/1900/2100 (download speeds to 42.2 Mbps, upload speeds to 5.76 Mbps
From what you listed, the Maxx should get GSM/Edge/HSPA/UMTS coverage there. And of course, no LTE.
The CDMA side of the Verizon phones is still "locked" so I also would not expect CDMA to work. In other words, if your carrier NEEDS CDMA, stop trying.

I've been through this with some trying the Moto X in India, and I've been through it while trying my T-Mobile and ATT sim's in my Verizon Moto X.
From what you are describing, it sounds like your APN settings for your carrier on the phone are not set right.
Example... When I put my T-Mobile SIM into my Verizon Samsung Galaxy S4, I get "unknown sim" and bars, but no network connectivity. Nothing works. By going into the mobile network settings on the phone and adding an APN with the T-Mobile settings, features like calling, SMS, data, etc. start working. I have had occasions where I thought I had the APN right, as calls and data worked, but MMS only partially worked (would send but not receive). When I do have the settings right, everything works. Similar thing happens on my Moto X with T-Mobile SIM.

Unless you have an active account with Verizon, and are trying to use their service when traveling, Verizon wont help you. In other words, unless you are trying to get your Verizon phone, working on Verizon's Global Roaming service, on your currently active Verizon account, they wont help you.
Even if you are a Verizon customer who is just traveling and popped out your VZW SIM in favor of using a local prepay sim to save data/voice costs, once you pop that VZW SIM out, they wont assist.
But you have received confirmation of what I said.. the GSM side is unlocked.
The SIM you are trying to use is from a GSM India carrier? As long as they only use GSM (no CDMA required), your only hope will be working with them. Telling them your phone is SIM Unlocked and going from there. Or finding a local message board for the carrier, and hope people are discussing use of "3rd party" phones, and you might get some help there.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.
I can't offer any more than that. Sorry.

I have now put in a CDMA SIM card, but run into another problem with that. I will activate that SIM on another phone and then pop it in the Maxx again and check. But CDMA should work fine as reported by other users.
But the problem is the GSM part, because that is what we need to get working.

That is bad on the part of Verizon. I have purchased a Verizon device off-contract and that device is a global one. So I am entitled to some support from them even if I am without a service plan.

Yes. Local carrier. And for now, there are three such XDA members who have been facing the same issue. In one case, a member was able to make calls and receive calls and also use data. Then after a few minutes, the SIM invalid message popped up.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.

APN settings are pretty easy. I did that with my earlier SIM and I got data working. There was no voice, so I gave that SIM back to the carrier and got a brand new nano SIM. Now, nothing works. The old and new SIM are for the same number and same service provider.

Right, you got just DATA working with the APN settings, but the correct APN settings are also needed for SMS, MMS, Phone calls, etc.
I've had an issue where I had voice but no data, and it was related to APN. I've had an issue where I had voice, SMS, data but no MMS, again, it was related to APN settings for the carrier you are using.
So good luck!
the problem we sorted out to get gsm working in india first the phone must be activated on usa to get it work on india so can anyone help us > @s_u_n
So, after using the phone for a week on GSM with all application updates installed, I can safely state that
1. Verizon activation is not needed for non-VZ networks to work (at least outside US).
2. A full FXZ was installed and it probably solved the modem configuration mess that the phone might have been. Perhaps it unlocked something?
3. Four corner activation bypass method was used (as described in earlier Motorola phones).
Either 2 or 3 solved the problem
There was nothing to do with APN. Data works even without any APN settings out here, just like on my Motorola Defy.

Is LTE CDMA and GSM?

Hi folks,
I live in a black hole of cellular signal. The only provider that has towers where I live is Verizon. I drive 45 minutes to work every day and over there both Verizon and AT&T have towers. I'm currently using a small, local carrier that uses Verizon towers and phones. I bought a Nexus 6 and want to activate it on straight talk. I thought I could use the IMEI from my existing phone, since it's a Verizon phone, but they say it's not compatible. They say they can activate it as a GSM phone, but I've read that if I activate it as a GSM device, it will not connect to Verizon towers so would basically be useless where I live. However, that doesn't really make sense to me since the Nexus 6 has both CDMA and GSM radios in it.
Does anyone know if I activate a GSM sim and pop it in my Nexus 6 if it will connect to Verizon towers? We do have LTE here, if that makes a difference Thanks for any help you can provide!.

dual sim issue... Verizon/tmobile

I've had duel sims running with no issue since I bought the phone. Now today all of a sudden the Verizon sim will not work in this phone. I've tryed switching positions.... And by itself... NOTHING... I put the Verizon sim in a Verizon phone and works fine...
Any settings or somthing I can check? This phone is begining to be more trouble than it's worth.
Are you sure a Verizon sim will work with this phone? Usually Verizon runs on the CDMA network. If the phone is GSM only, the Verizon sim reverts to voice over LTE. As far as i know, this phone does not support voice over LTE.
I'm just guessing.
An educated guess though
But check the data network settings.
Play with the dual sim settings.
Sometimes one of my sim slots just disconnects for no reason

It seems like the vivo nex snapdragon 845 version (the pop-up camera one) is missing a band 13 for 4G lte. Does that impact the connectivity in any way on Verizon?
Also is your model the chinese rom or the global rom?

XZ Premium / LTE on AT&T? AT&T says I'm only using 3G

I'm being told that my device is going to be booted off AT&T because my XZP is only running at 3G (according to at&t support engineers). I find this hard to believe.
I had some initial issues with the sim because I used the sim from an older phone, which could only do 3G, so it wasn't registered on their network as capable of anything else. The jerks in the store were of no help, and even got attitude with me about dropping my sim into a new phone to see if it would register. Luckily, I had a bud who had a brand new LTE AT&T phone, so I popped my sim in there, let it register, get access to all their new/current bands, and then I put the sim back in my XZP... lo and behold, all the capabilities were unlocked.
I have been running the at&t apn for high speed, phone started using 4g+ when the LTE rollout finally got fully deployed.
In trying to run down if AT&T is full of crap or not about kicking my phone off the network that is "only using 3G"... I came across this https://apn.gishan.net/en/apn/att/sony-xperia-xz-premium
It shows I should have a bearer of LTE, and I do not. I have 4G and all of the older network types, but no LTE. Does anyone else have this? If so, what network are you on? My phone should be current on its updates, as old as they are...
Maybe I need to drop this sim into a current gen phone again and let it register on their network?
Any ideas/feedback is appreciated.
