If I currently have consumer cellular which runs on at&t can I buy the walmart mobile version and just stick in my consumer cellular sim?
You can't use any Tracfone device on other carriers unless you pay $150 to unlock it or use service for one year on the device with TracFone.
No. Walmart mobile works on T-Mobile btw.
Though that device can be used on Verizon, At&t, T-Mobile, which ever carrier you like.
It's basically an unlocked device to use where ever you want. But within TracFone brands.
