Lumia 640 Dual Sim - No network found

[alinauman97]

Hello Windows Central community!

I have a Microsoft Lumia 640 Dual Sim, running Windows 10 Mobile build 14393.67 (Production Ring). I did reset my phone after the Anniversary Update, but for the last two days, I have not been getting any cellular network signals. I have only one sim active, and it was working fine till Wednesday afternoon. I suddenly stopped getting the signal and I wasn't in any no coverage area. I have tried soft resetting and removing/reinserting the sim card but to no avail. I want to avoid a hard reset. What should I do?

Any sort of help will be appreciated! Thanks!

Just tried putting my SIM in an older phone. Not getting any signals there either.

Dead SIM, go to a carrier rental and ask for substitution, that's istant , no numer or plan change (but they ask some money for the new one)

Yeah, might be. I contacted my carrier's support, and they said that there is some issue in the region. If it does not get fixed, I'll go for a new SIM.
