I have Iphone clone and I get ''no service'' when my AT+T sim card

I also had purchased an Iphone clone not to long ago. My service provider was AT&T. 90% of the time when my SIM card was inserted the phone would read "emergency mode". I would have no service, I wouldn't be able to receive or send any calls or text messages. I talked to AT&T representatives who would solve the problem for short periods of time but never gave me a permanent fix. I immediately sent the phone back to the seller. I have been doing a lot of research on these Iphone clones and I have seen quite a few times that people have problems in this area, not being able to have service. Also, what you have purchased and think is a genuine Iphone very well may not be. Many models of these Iphone clones now have the Apple symbol on the back and even have the Apple logo displayed on the screen when they start up. This being the case, you may very well have purchased a fake Iphone which would lead to problems with your service provider. I'm not sure how to fix the problem, and for this I apologize because I know how frustrating it is not to have service. But, I can tell you that your best bet may be to return the phone and try something else. All I've heard is that the genuine Iphone is the best way to go. Because these clones are made by independent manufacturers and not sold through AT&T, even though they may seem nice, many people have constant problems with service. Good luck, and if you find an alternative solution please let me know!
