There is only one question and that is does the IMEI pass the Virgin Mobile checker?
If it does you can switch and keep your number and phone. Your sim card will also work here since you are using the CDMA service on Ting.
Hi there, Papageorgio. Let's take a closer look. You must access https://www.virginmobileusa.com/plans/bring-your-device.html to check device eligibility. Then, you can order a SIM kit after passing eligibility. Is your device unlocked? ~AmyM25
