Bought my phone in KSA (Jarir), did the 5min call and took it back to South Africa.
This week, after months of successful use with South African SIM the phone says "no service, strikeout-circle icon" and both SIM trays say "Unknown" SIM. This is true for 2 different providers in RSA.
As others also asked before on this thread; how do I check if this is a region lock issue or hardware issue; is there a *# code I can use to check the "lock status"?
I don't understand. My s8 is unlocked to any network. I'm with o2 in UK. I went to Burma and put Burmese sim in and it didn't work. I'm back in UK but don't have Burmese sim with me so how can I unlock region. I am confused about people saying use my o2 sim for a 10 min call or something to deactivate region lock. I always use my UK sim so shouldn't it be unlocked. I'm off to Burma again soon and need the Burmese sim to work urgently. I don't want to risk being over there again and it not working w/o is there anything I can do to fix this from UK. If I have to make a call in Burma from my UK sim it'll cost a fortune and probably won't work anyway
So I must use my UK sim in the country overseas I'm in for 5 mins then I need to put that country's sim back in and it should work? Can't I do anything in the UK to make it work before I go abroad and try there?
You'd think it would be that easy. Carphonewarehouse say their phones are unlocked o2 are saying that I need to talk to Car phone warehouse and they are saying only manufacturer can help. Spoke to samsung and they can only help with region not network and they can only help in same way as you've said. I'm going round in circles and just need resolve before my next trip as I'll be away indefinitely.
