Today, AT&T came out with a press release stating that 5G service will be coming to Cricket Wireless. Here’s the relevant bit:
On Aug. 21, Cricket Wireless customers will be able to activate 5G service on the Samsung Galaxy S20+ 5G. More details soon!
As far as I can tell, Cricket has not yet updated its own web pages about 5G.
I expect Cricket subscribers will be able to access both AT&T’s sub-6 5G and AT&T’s ultra-fast millimeter wave 5G. While the S20+ will initially be the only 5G phone offered by Cricket, we should soon see the carrier offering more 5G-compatible devices. It may also be possible for Cricket customers to bring their own unlocked 5G phones to the service.
