Re: Digital vs Tri-mode phones?
Rukshan,
I'm an IT professional and followed everything you provided about the CDMA/TDMA signaling differences and the frequency information. I hope you may be able to clarify something that a store technician told me that goes against the grain.
Based on the information you provided, a phone that has say LTE 750, WCDMA 850/900/1900/2100, CDMA 850/1900, and GSM 850/900/1800/1900 capabilities: if it leaves the contracted carriers tower footprint and roams into another carriers footprint that has one of the technologies/frequencies that the phone is capable of communicating on, will it be able to use the other carriers technology/frequency to establish a call? (I understand that there may be additional roaming charges, but will the greater technologies/frequencies capable phone have a better chance of roaming than a phone with fewer modes?
Thanks,
Rusty
