Whatever you do, don't put a Freedompop SIM in your phone. I did and now my new iPhone is useless.
I'll explain. When I bought my new iPhone 5 recently, I opted for a SIM-only deal from Freedompop. Trouble was, the coverage in my area was completely useless. The phone was unusable for calls and barely if ever connected to the internet. So I sought a new supplier.
However, when I plugged the SIM from the new supplier into the phone it didn't work. My iPhone had locked into the previous Freedompop SIM and no others would now work in it. Despite this being a seemingly common occurrence in new iPhones, Freedompop was unwilling or unable to do anything to unlock my phone to allow me to use the new SIM.
I have been back and fore with their customer services department for over a month to try to sort this out. At one stage, my repeated requests for an update went unanswered for TWO WEEKS, though now they've come back and told me they can't help. The local shop that unlocks phones can do nothing about it because Freedompop is too obscure a provider for them to have any unlock codes for.
The upshot is, I'm sitting on £500 of new iPhone 5 that has been rendered completely and utterly useless by Freedompop. I strongly recommend anyone thinking of registering with Freedompop not to do so. You might lose you phone, too.
