You'd need to find a CDMA model of the phone, or something close to it, and then you'd have to find a shop with the ability to rewrite the phone's control software to work with Virgin (called "flashing" the phone). No GSM phone will work with a CDMA carrier though, you'd have to find something from Verizon or Sprint or other CDMA carrier.
I've seen the specs of the Lumia 635 and am under the impression that his phone is compatible both GSM and CDMA carriers. I bought a 635 prepaid Virgin USA phone with service provided by sprint. It is locked to Sprint and will not recognize any non-sprint sim cards, even through service with CDMA carriers doesn't require a SIM, just a service agreement.
I read that unlocking sprint phones is virtually impossible because they don't lock the phones to Sprint only, they lock the phone to CDMA only, Sprint only, and lock the sim card slot, so that their phones don't recognize any non-sprint sim cards and don't prompt you to enter an unlock code to use to use the phone with the carrier of the sim card you inserted. I have tmobile as my family plan phone and would love to unlock the nokia, however, I am perfectly content to keep it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
