Will prepaid AT&T SIM lock my previously-unlocked AT&T Android phone?
Hello.
I have a previously unlocked LG v20 phone from AT&T, that I took overseas, used with other carriers for several months and bring back to the USA.
I recently bought an AT&T prepaid sim so I can use my phone for some time and then I'll come back overseas for other months and use other carriers again.
Will this AT&T SIM card lock my previously unlocked device? Can you please confirm if locking or any other side effect or lock time will happen?
Thank you very much.

I haven't heard of any such automatic locking happening other than a newly bought unactivated phone locking to the first SIM inserted. A phone that's been in use and unlocked stays unlocked.
