A:Answer Your question is unclear. If you activate this Mobley device, pay for service, and install it in your car (on the OBDII port), you will have a wifi hotspot in your vehicle. You can connect to this wifi hotspot with any wifi-compatible devices including phones, tablets, laptops, or desktops (with wifi adapters). It doesn't matter who you use for a cell carrier on that phone, if you're connecting to this device with wifi. I hope that answers your question and helps others.
