I'm planning to buy Xperia Z2 (D6503) but I couldn't find clear answers for below:
1. Is 4G sim card GSM or CDMA based service?
2. Are Xperia Z2 4G bands compatible with Verizon's bands in model (D6503)?the specs shows band 4 &13 is already included in D6503.
3.How can I get the APN for Xperia Z2 in order to activate 4G LTE?is it from Verizon or another source?
Big thanks in advance for the help and my apologies for bad English.
