Hi all,
I've just purchased a Verizon G998U with cracked front screen and back and found that the phone is google locked - FRP Locked. According to the seller, it was Verizon unlocked prior to the sale. Tested the phone with my local Malaysian SIM Card and I was getting signal from it prior to getting the screen replaced and FRP unlocked.
I have managed to get the FRP Lock removed and a factory reset later allows me to setup the phone properly with my own Google Account but when i'm putting in my Malaysian Sim Card, it says that this is not a Verizon sim card.
Any ideas on why this is happening? Will an sim unlocked phone be reverted back to a locked phone after FRP lock is removed?
Thanks in advance
Ask the seller for the unlock code used before
Noted miravision, what do i do with the unlock code then? Putting in my Malaysian sim card and rebooting the phone does not ask for any unlock code.
Depending on whether the seller used an official unlock authorized by Verizon or used unofficial means, your seller should help you further in good faith
Noted with thanks, miravision. I will check with the seller and will update once i get a feedback from them
Update on the testing done to the phone. Didn't managed to get anything from the seller. But did some interesting testing with the phone. I've got 2 sim cards with two different provider in Malaysia - Celcom and Yes.
Flashed the phone with the U1 XAA software and managed to setup the phone with Yes sim card with VoLTE running and Internet working. As for Celcom SIM card, no signal at all and tried playing around with Samsung Band Selection App, managed to get the sim to connect intermittently with VoLTE and Internet working. Removal of sim and reboot of the phone will sometime changes the Celcom SIM to no signal at all and manual searching of the Celcom network also doesn't show the selectable network and only shows Yes 4G network.
So from the testing above, can i presume that the phone is sim unlocked? If it's unlocked, why can't the other sim from Celcom can't be detected consistently?
Anyway, the telco info is as below
YES - LTE Band 20 (800 Mhz), Band 38 (2600 Mhz), Band 40 (2300 Mhz),
VoLTE Support
Celcom - LTE Band 1 (2100 Mhz), Band 3 (1800 Mhz) , Band 7 (2700 Mhz) - VoLTE Support.
Hopefully can get some insights on what is actually going on.
Thanks in advance

I am a n00b in the subject of unlocking phones to use on other networks etc.
Is there a possibility when the SPL is unlocked that we could use this on any GSM network since it is a 'world' capable phone with the GSM radio and a SIM card?
I have used a lot of WINMO phone son VZW and I flash and unlock quite often. Just had no idea how this process worked. sorry if this is a duplicate of any kind
thank you
You can call Verizon and ask them for the unlock code to your phone. The number is 1-800-711-8300, option 2 I believe. Either way you'll end up talking to a human who can do that for you. Then you'll enter the code (code A) in All Settings > Personal > Security. According to others, this unlock on the SIM will remain, even after flashing with a custom ROM.
no software to unlock the sim card, i don't want to call vz
I can buy unlock code for Imagio.
Why dont you want to call verizon? They are perfectly happy to unlock the sim for you as long as you dont have any problems with your account like delinquent payments. I called and had both of my phones unlocked in minutes and tested my ATT sim card, worked great on the aTT network
GSM 3G on america?

Did you see if you had E or 3G or H?
I've looked at the specs but haven't found the GSM 3G bands that it has.
Just this:
Digital Dual (CDMA,PCS) /1X, EVDO /Rev.A <---- perfectly clear
GSM Quad Band (GSM/GPRS/EDGE) <---- perfectly clear
WCDMA / HSDPA / HSUPA <---- not clear if it has 850mhz here
I guess it doesn't have 3G in 850mhz but I still have hopes.
Regards!
I only get "E" - my SIM is 3G capable, but the corporate plan is text-only. In other words, I can't say for certain if it will get 3G speeds. HSDPA is available here in the US, so it should be possible for an Imagio to have 3G in the States.
I called yesterday, told them I would be going overseas, they gave me the unlock code. Simple as pie. I can use my neighbor's AT&T sim card without any issues minus stuff that is Verizon specific.
The SIM unlock was easy and successful. Just call Verizon at the above number and its a done deal in 30 seconds. Will try my wife's SIM in it later.....woohoo....
because i dont have vz wireless phone number, but i need to use the t-moible or at&t, i call them, but they need me vz wireless phone number... i dont have, they not unlock for me
as i was told u are able to get it unlocked verizon will do it if ur account is 3months old and in good standing... also as far as using it on gsm not sure as of yet but will say tmobile basic signal i E in an area where out of ur basic ntwork jumpin off of another tower it will put u on H or even G but there is no 3G

H is HSDPA, which is 3.5G (faster than 3G... 7.2mbps compared to 1.5 mbps or something like that)
Edge is like 0.3 mbps and GPRS like 0.1
not really sure, but you get the idea.
Here in Mexico we have HSDPA but never get above 2mbps, at nights we do peak at 3mbps but avarage is still at much 2mbps.
Did I do something wrong?
I told them I was going over seas, I gave them my sim number and they said I was all set to go over there. Does this mean my phone is unlocked, I didn't have to put in any numbers. I will hate myself if I said the wrong thing. And if I did it right then how do I switch between sim cards and cdma?
For you phone to be unlocked they would have to give you a number to enter.
To switch between sim and cdma, go to settings -> phone -> network and change it from global mode to GSM

Not true, works fine with t mobile and at&t, didn't enter any numbers did it all from their, weird, but whatever.
I think a few things from the last three posts need clarification:
1. When you call VZW Global Support, they should have given a security code to unlock the SIM. It is a string of numbers. It is not a phone number.
2. Once the SIM is unlocked, if a SIM is present in the phone, there is no guarantee that switching back from GSM/UMTS to Global will switch the phone back to CDMA. There have been times where I've done that, and the phone has stayed on AT&T (my employer uses AT&T). I think a better method is to use either CDMA or GSM/UMTS, and to avoid the Global setting completely.

On item number 1 I would agree with you ignore my experience because even my friend who unlocks all kinds of phones for metro says it is a weird case. I have never received any unlcock cod yet it says "sim security unlocked" probably will be screwed up if I ever want to flash or reset it but whatever.
On number 2 I can't agree with you because I bought an at&t go card just for sh**ts and giggles and I have no problems, infact I can switch between the two while the phone is on, done many tests. But if anyone else experiences this issue I would like to know.
I have never heard an unlock like that. But could be... like an 'on air update'... Most times is a code or the frown upon methods (connect it to a PC or a box).
If any one wants to know, no it does not have GSM 3G for 850mhz band, not 3G with ATT and others in the world that uses that band. Tested it myself.

Even if you run at&t 3g it is much slower than verizon's. Either that or safari renders slower than s**t on brother's Icrap 3g. T mobile's is faster if you can find their 3g coverage, good luck.
PS I am still looking for internet connection settings for tmobile as I sold an unlocked imagio to my buddy and he can't get the data connection working.
does anyone ever solve de 3G problem with the 850 MHZ band... I live in Venezuela use movistar i ve the imagio sim unlocked can´t get 3G due to band restriction
[Q] Unbranded unlocked Milestone cannot connect to data service on AT&T or T-Mobile
I bought a M1 off Amazon about 5 months ago. I don't have a data plan in my home country as my SIM is company provided without data. I get by with wifi most of the time. Over Christmas while in Miami, I tried my nephew's T-Mobile SIM from his HTC and I tried an AT&T SIM with $5 data - and neither would connect to EDGE or 3G. The phone could still make calls though. Anyone have any idea why that would be? I have no clue as to what region the phone would belong to -so I do not know what GSM frequencies it operates on. Motorola's website specs says that the GSM version operates on 850/900/1800/1900 MHz - and supposedly AT&T 3G operates on 850 7 1900 MHz -so I can't figure it out. Could it be something software/firmware related?
It's a APN issue if you can make calls but cannot connect to mobile data. Check your provider's APN configuration. (Just google it.)
yeah. check your apn. for stock rom and some other mods apns cant be configured automaticly
Hi there,
I've recently got a Honor 4X CHE1-CL10 dual sim card smartphone from china. We manage to put the custom mokee 6 rom on it and it work well. However the only the sim 1 location have 4g options and if I put any card in it ( vodafone, o2, ee) it says invalid card.
Is there something I can do to about it so it will work, or I can only use the 2g option?
Thanks for the reply,

As per phone specification:
http://www.phonemore.com/phone/huawei-honor-4x-che1-cl10/2185
Slot 1: TDD-LTE: B41; FDD-LTE: B1/B3; CDMA: BC0; GSM: 900/1800/1900MHz(international roaming only)
Slot 2: GSM: 900/1800/1900MHz
Mostly likely this phone is not match with your carrier's 4G network... which means at best you can only use 2G network...
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?

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?
Phone works fine with a particular network (Vodafone). When I insert a sim card from a different network, there is no reception and it says emergency calls only. However, it does not ask for an unlock code so I don't know if the phone is actually locked and how to input the network unlock code.
I purchased my Mate 20 X 5G from Vodafone UK and it works with other network SIMs. Vodafone don't lock their phones to their network.

My P30 Pro was initially working with my Three sim. Then, after a couple of months, it randomly stopped working and said emergency calls only at the top of the screen. I tried the Three sim in another phone and it was working fine but wouldn't work in my P30 Pro. Only Vodafone sims now work in it. However, I'm not entirely sure it's blocked to other networks because when I insert my three SIM, it doesn't prompt me for a network unlock code.
