I am guessing to the layman this means something like 3G or 3.5G…but we would always want the latter, right?




You must specify the correct value for your cellular carrier.

Why it is not automatic? Because these 3G, 4G things are never standardized and it is hard to do it fully automatically without a big and updated database. Some settings are not be able to detect as well.
