Wi-Fi calling on iPhone China variants with non-China SIM cards
Hi, i'm planning to buy Iphone in china mainland because it's not available in my country. I read that Wi-Fi calling is not supported in iphone china variants however i was wondering if i bought my iphone on China mainland, would the Wi-Fi calling work if i'm using my local sim card outside china (back in my home country)? is it depends on the simcard or is it a built-in feature?
Please help, i've been searching but i'm not able to find any answers for those of you who bought your iphone from china and using it in your own country, please let me know, thank you.
