Hello.
I have an Atrix HD from ATT, I bought it unlocked at Ebay. I used it with my ATT sim Card, then with Movistar in Colombia for vacations and everything was working great. Then I came back to the US, used a T-Mobile sim card and now I can not use any other sim card. The only one it accepts is the T-Mobile one and it works fine. If I pop any other sim card it gives me no signal (a white cross appears in a red circle where the circle bars should be).
My phone is rooted but I have not flashed any ROM or done anything else beyond installing Superuser and Titanium Backup. I already did an internal and an external reset and none works: The only sim card that gets signal is the T-Mobile one. Called T-Mobile and they said they cant help me since the phone is not supported.
My hint is that somehow the T-Mobile sim card switched my frequency bands. Whats funny though is that now I am in Colombia and when I insert the T-Mobile sim card and check which network is my phone connected to it shows Movistar and the signal bars are great. If I pop up my Movistar sim card it gets no signal at all.
Any help will be greatly appreaciated.
You must have setup the sim card lock disable that and then try putting in another sim

I got a Razr I XT890 running retail 4.1.2 en.EU rom and despite bootloader unlocking (out of warranty now and rooting neither of two sim cards for Union Wireless (Wyoming, U.S.A.) nor one for Verizon show as recognized: a sim icon as well as the signal bars both have red, crossed circles over them and "Emergency Calls" displays on the bottom of the lock and home screens.
I took it to my carrier and they suggested that perhaps the sim card reader was damaged but I absolutely love this phone; has anybody had or overcome a similar problem?
Dunno if this is true, but is the razr i not a gsm phone and u need a cdma phone to get it to work in the usa? So only the razr m works there?

Verizon is definetely a CDMA carrier, meaning you absolutely need a CDMA phone that is from Verizon directly, same with Sprint in the U.S.
You can either use AT&T or T-Mobile or H2O in the U.S. with your Razr I, before you buy anything, double check on which frequencies those networks operate (cause its different) and then check which one of those are covered by the Razr I.
The Verizon sim card doesn't really do anything, they provide it for their customers who go global, for domestic service all information gets programmed directly into the phone by Verizon when you register a phone with them. Most Verizon phones don't even habe sim card slots, cause they want you to stick with their carrier til the end of time, some phones do, they call it "global ready" then.
Hello everywhere! I read online that the Moto G 2014 sold by Wind Mobile Canada comes unlocked, so just to test it out I put in a friend's Bell Sim card, which the phone detected right away. Now when I inserted my Wind Sim card back, it does not read it, there is a constant error on the lockscreen: "No Simcard- Emergency Calls only". I have tested my Wind Sim in my wife's Nexus and it works fine. Her Wind sim card, however, does not work in my phone either, but Bell/Fido etc work just fine.
It seems really odd, because my sim card is not defective, neither is the phone. Any suggestions?
I have restarted, turned it off for a while, factory default but no cigar.
Thanks a bunch

make sure the APN settings are correct

I have a friend who is on MetroPCS here in the States and he can't seem to get his SIM card to be seen by this device. It was originally meant as a going-to-college gift but has turned into more of a headache than a gift. Yes, we know that MetroPCS uses T-Mobile's towers and the Blu R1 HD is entirely compatible with it...we just don't know why his SIM won't work. Originally we had to get a SIM adapter for the Nano SIM to make it fit the MicroSIM slots, but regardless of which slot we put it in, the phone is stuck on "Emergency Calls Only".
If anyone could help, that'd be a lifesaver, as he starts school on the 22nd of August.
Things we've tried:
Going through the searching for operators function in settings->more->cellular networks
Entering different values in APNs (settings->more->cell networks->APNs)
Restarting a bagillion times
Changing preferred networks
Repeatedly tapping on which sim slot to use for data and messaging
Going into Data Usage only to not find the Cellular data option next to MetroPCS
Did you try another SIM? It's possible that the phone itself is shot. Otherwise, the SIM could be shot. Did you try the SIM in another device? It seems unlikely (however, not impossible) that the SIM and the phone just don't like each other. It's also possible that your adapter is positioning the SIM incorrectly. You should be able to get a good one by going to a T-Mobile store. They usually have a few laying around.
Doesn't Metro require you to give them the phone's IMEI before being able to use the new phone? Contact Metro CS and tell them you got a new phone that you want to use and give them the IMEI
If you alrdy did that then try using another active SIM (borrow from friend/family) and see if that works fine with the phone in case the phone is defective
I have Metro PCS and this phone. You need to call MetroPCS and give them the IMEI. Make sure you give them the right IMEI as there are 2 SIM slots on the phone - each with its own IMEI
We went to a T-mobile store to get a good adapter for free.
Thanks, we'll try this!
It worked. His phone is now setup thanks.
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?
