The TIDRADIO TD-M15 is a push-to-talk radio that runs over 4G LTE instead of licensed radio bands, so range is limited only by cell coverage. It ships with a built-in SIM and a year of free data, then $20 a year. It is IP67 rated, has a 3000 mAh battery and a 200-channel list managed in the ODMaster app. The only price on record is $69.99 at the listed store as of November 1, 2026, so there is no recent range to compare against yet.
