If you are not sure if your Straight Talk phone is using the AT&T, Verizon, or Sprint network the best way to find out is ask Straight Talk customer service. You can call them on the phone but I think it is better to use Live Chat. Visit https://support.straighttalk.com. Click the Contact Us button and choose Chat Live Agent.
AT&T, Verizon, Mint Mobile all offer plans that could save you $5, $10, or more per month. Many of these services offer most requested features such as Mobile Hotspot, Wi-Fi calling, and Visual Voicemail.

Ask the agent…
“Hi, My phone number is (###) ###-####. Can you tell me if my phone is using Straight Talk’s AT&T, T-Mobile, Verizon, or Sprint towers?”
Make sure to replace (###) ###-#### with your phone number.
If you need a new SIM you can order one from Straight Talk for a dollar. If your phone is using the Verizon towers, see Transferring Your Straight Talk Verizon Service to a New Phone
