But when it comes to internet data, usually there are limits hidden in the fine print. 4 T-Mobile meanwhile won’t have C-band available until the end of 2023-so while it’s leading the 5G pack now, you may end up with better performance on AT&T if you live where C-band is near.Ī lot of cellular providers-not just AT&T and T-Mobile-boast having “unlimited” cell phone plans, which give you unlimited talk and text along with other perks. C-band (3.7–4.2 GHz) is considered by wireless experts to be the ideal channel for 5G performance, because it can deliver incredibly fast speeds (upwards of 100 or 200 Mbps) over a relatively wide area.Īt the start of 2022, AT&T’s C-band availability was limited to just a handful of cities, but it’s expected to expand to dozens more by the end of the year. But beginning in 2022, AT&T has begun slowly rolling out C-band channels across its 5G network. T-Mobile mostly has built up sub–6 GHz 5G, and it’s performed great so far in doing so.

And in the coming year, that may give AT&T the ability to vault past T-Mobile in terms of speed and performance-at least in some areas.ĥG operates over a wide range of radio frequencies, including sub–6 GHz bands that deliver 4G–like speeds over a wide range and millimeter-wave bands that give your phone impressive, gigabit-plus speeds but only in relatively contained areas (like stadiums). While T-Mobile has a larger 5G network and faster 5G speeds, AT&T has one technical advantage in that its 5G network supports a wider range of radio channels to support 5G phones.
