t mobile samsung galaxy s4 4.3 how can flash to verizon wireless

[jwynegar]

you would have to unlock the phone (contact Verizon for unlock code), change some phone settings, and then you can use a T-Mobile SIM card, but beware that your data will not work on 4G.

Ok first verizon 4G LTE devices are unlocked from the factory and he would have 4G HSPA+ but he has a T-mobile devive he is wanting to use on Verizon which is not possible because t mobile is a gsm carrier and verizon is a cdma carrier so the phone would have to have cdma capabilities which no phone sold by t mobile does so short answer it's impossible
