ms345 are misteriously losing network registration - GSM-Forum

yurais · 11-24-2015, 19:10

I have got some LG leon ms345, I have unlocked it with Activations service for the device unlock application to work.

After unlock all is ok, but weeks later or days later, some phones, are losing the network.

you can find the network if you search for it manually, but the phones are not registerin in the network, not even for placing emergency calls.

I have done so far:
Flashing the phone
Writing QCN from working phone
Writing NVM from working phone
Factory Reset
Change IMEI, just to be sure is not barred

Any suggestion?

Hello.

Unfortunately we can't say what could cause the problem with Network after phone was unlocked via service. Try to contact with supporters of service, which You've used to unlock the phones.

I don't think it is related with the unlocking service,, since some phones has been working for a couple of months just fine until it suddenly loses the network.

You see bars in the network signal strength but no incoming or outgoing calls are available.

These actions should've fixed any kind of problems with Network, which could be caused by phone itself. If neither of them solved the issue and You are sure that service, which You've used for unlock is not cheating - check phone's HW.

Am sure the service has nothing to do here, other phones are still working fine. Also the phone doesn't make emergency calls, this means there is no any kind of communication with the network.

Check the imei, it may have gotten blacklisted since the unlock for whatever reason... that can cause network loss.

I send it to USA and it works there with AT&T sim card, Here on Cuba does not register in the cubacel network. I want to know why is that, I'm not the only one with that problem in my country

yurais · 12-23-2015, 02:00

It is intrestingf to know this, so, phones works in the United States.

did you check if maybe the phone is working on 3g-4g mode and not in 2G ?

am just trying to debug.

ernestico911 · 12-23-2015, 17:23

there is only 2g in cuba my friend, if the imei was blacklisted by metro there is no way to register with another op on US

yurais · 12-23-2015, 18:11

i know, thats why we cant test in cuba if the phones are working on 3g networks.

so, the phone which is in USA now, will also work if it is forced to 2G only mode?
