Sim locked Iphone7
I have a new replacement iPhone 7 not sim locked as it is illegal in Denmark where the iPhone is bought. The iPhone is bought from one provider and are using a second providers sim card with no problem. Now the iPhone is for some reason been locked to the provider of the sim card and cannot be used with other sim cards at all. The sim provider says they don’t lock phones and therefor they are not able to unlock it? Apple support can tell me it is the sim card providers ID the iPhone is sim locked with, but Apple are not able to unlock it. What to do?
iPhone 7, iOS 11.2.6, IMEI **********
