What do you guys use for communication in your truck camper?

I personally like the dedicated phone number for texting where I can text anyone and anyone that has the number can text me through the satellite..I don't understand the email nor need it..I was worried about reception but it gets reception in the house and the truck camper by a window... Best $199 I've spent in a long time..

Once I get the rest of my solar hookups from Amazon for my TC solar, I'm heading to places a cell won't work for the real test..lol
