Some unlocked phones sold online indicate compatible with Verizon while others do not. Can anyone tell me how I can determine is an unlocked GSM phone that is being sold online is compatible with the Verizon network? It seems many of the vendors selling them are not sure or are mistaken. I had one vendor give me the imei and tell me it was compatible, but the Verizon compatibility tool indicated it was not compatible. I do know I can enter the IMEI number on the Verizon site, but it seems some of the vendors do not know the IMEI numberhe phone they woul ship me.. Also, is the imei identification tool on the verizon site 100% accurate?
Also,in general why are some unlocked phones not compatible if using LTE technology?
