A:Answer It should work on Cricket, which uses AT&T's network, however OnePlus does not have 5G Ultra Wideband antennas for bands n258, n260, or n261. But 5G UW is limited mostly to large cities and has limited range. 5G UW is really most useful if you plan to use your phone as a hotspot and connect multiple devices to it for Internet access. OnePlus supports all other 5G bands and will just use normal 5G in areas that happen to have 5G UW.
You could possibly have an issue activating the SIM from Cricket on OnePlus because it's missing the 5G UW antennas. This happened to me when trying to activate my OnePlus on Visible which uses Verizon's network, but I was able to work around it by first putting the SIM card into a Samsung phone (which all have the 5G UW antennas) to activate the SIM. Once the SIM was activated, I just took it out of the Samsung phone and put it into the OnePlus, and it worked just fine after that.
