I tell you a bit about my situation, I have a Xiaomi mi 8 with a strange problem, it is dual SIM but only SIM 2 works since the imei of sim 1 appears 0, I tried to edit the QCN file but when restoring it to the computer it remains 0 imei 1, and also that with SIM 2 I cannot connect to 4G / LTE in my local operator that uses Band 4 and 27

I have a Huawei mate 10 lite, and when I enable data on sim slot 1 it will lose its signal and become emergency calls only. But when I enable data on sim 2 both works just fine. I just can't use data on sim 1.
Both are 3G sim cards, so I got a new 4G card and it worked for 2 days. And then 1 day it stopped. It says emergency calls only which every sim slot I use. I don't know what is going on.
Can someone please help?
Hi Guys,
I have a Note 8 and I had it sim unlocked thru an online service. I was a bit dissapointed when I found out that I was only able to use my sim 1 as call and text only like the sim 2 slot after the unlock and I could not use it for data 4G. The tech guy from the sim unlocking service told me its with the software of my phone from the original carrier that has not allowed me to use data on 2 sim slots except its original carrier. Can anyone please help me how to fix and enable 4G to work on either yhe 2 sim slots?
Thanks very much!
I don't think that is carrier related at all, even my unlocked/international version only allowed 2g/3g in the second sim slot

Check that your APN settings are correct for your provider.
I would imagine sim 1 would allow 4g from any carrier as long as you have a 4g sim card/plan
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
