Stronger cell connection one way or the other? | Tesla Motors Membership

Another, “you are not going to like it” but, I would try a different phone. I’d go to at&t (since Tesla’s are using at&t) and get a Pay-as-you-go phone with a one month plan. Try it just to see if it makes a difference. I know you said, you get 4 bars on Sprint, but you are looking for anything that makes a difference. Even if it doesn’t make technically sense, it might make a difference. at&t doesn’t work? Take it back, they have a 30 day return policy, and you don’t need 30 days.

Have a friend that can come over? Better different cell carrier. Install the Tesla app on their phone, login with your credentials. Test the summon. Better? Good. Not? Delete the app and it protects your password. Cost nothing to try.

Do you have WiFi in your garage? If you do, turn on WiFi without the SIM in both your Sprint and the at&t phone and use its WiFi connection to the internet to see if it makes a difference for Summon. Who knows? Just might.

And try the same with Verizon Pay-as-you-go. Maybe these won’t work, but cheaper to try than buying a WeBoost that likely will work.

Not related to your problem: I keep a cheap burner Tracfone (no cell service) in my garage. Charge it once a week. I have the Tesla app on it, and use it WiFi wise. Use it when I don’t want to go back in the house to get a fob. Its for “special occasions (emergencies)” And I created a Google Voice account, under a Gmail account for the burner. From WiFi, I can also make a WiFi phone call over Google Voice if needed. No cell service. With no cell service, I never pay a monthly bill, but have a simple smartphone and WiFi connection and can make cell phone calls whenever.
