Have a trusted friend pick up "held mail" at Post Office once a week and notify you of important mail. They could then email it. No way to get mail forwarded to SXM. Keep your phone on airplane mode and call using wi fi.
I have Verizon service and when I arrive to SXM, I turn off the airplane mode and just turn off my cellular data. Then I can receive important calls and messages. No charge for unanswered calls, so I return them on Wifi calls or FaceTime. The charge for incoming text messages is 5 cents. For a 3 week stay, my bill has always been less than $20.
No help on the mail... I know they offer the free service to email what they are holding, but not sure that would be a big help if you couldn't open it. We have all the bills that we can put to autopay so we don't have much that isn't automatic these days.
