My friend bought me an iPhone 8 plus from US. He told the sales officer that he will bring the phone back to Malaysia. The sales officer told him that the phone was unlocked. When I received the phone and try to activate the phone, an error "Sim Card Invalid" pop-up. Like the picture attached. Can I know is there any way I can solve the problem?

Most probably it was only unlocked for all US telco only and not worldwide Telco. From what I know, iPhone will be locked to ONE telco only in US. The "unlocked" part is most probably means unlocked for all US telco

I seee. Is there a way to unlock the phone?

i’m afraid Gevey sim is the only feasible option.

Gevey? Is R-sim the same thing? Can i know where can i get that ?
Thanks

This. Try to Google around

Have you tried asking your local telco?

AFAIK US version having different GSM from M'sia. Need to really check on this bro. Whereas if purchase iphone say from Sg or Hong Kong or Indo, no worries as the GSM will be similar/same for the region. Anyway, hope you get it sorted and able to use the phone.

i'm having malaysia set 7+.... and only recently i'm this same error as well... and i would need to restart my phone to get back signal...
is there any problem?

its unlock for US set only. previous i have this issue with ip6+ nothing can be done. waste my money for buying it, so i refund and get other phone

You need to find a phone unlock center

maybe try eject your sim and sit it back properly before putting it back.

i ended up getting a replacement sim card from telco... >.> costing me RM10...

I have currently same problem with unvalid sim for iPhone 6s.
It's by an European provider, does anybody has a recommodation where to find service to enable sim for Malaysian providers, e.g. Celcom?

Can PM me
