We are staying for a week at Kamp Klamath right along the river in Klamath CA. This is about 2 miles from the Pacific Coast.
We have found that we have absolutely NO TMobile coverage in this area. No phone even except emergency calls. The RV park does have wi-fi which is helpful but it’s not real reliable. We checked the TMobile coverage map and found that there IS coverage right at the coast, so every day we are driving a few miles down a narrow road through the dark forest to get to a vista point on the coast. From there we can walk a little ways to a picnic area where we do get coverage. This is when we make any needed phone calls, check for messages and also check our email and whatever else we need to do online.
We stayed at another RV park just a ½ mile down the road a few years ago when we had Verizon and we had no problem with coverage.
So, TMobile – saying you have the best 5G coverage isn’t worth much when a customer hits an area that requires a drive and sitting at a picnic table just to make a phone call!!
