How to use the Coolpad Quattro 4G on family mobile which is through Walmart & T-Mobile?

I ahve been told that I need to have my coolpad quattro re-programmed-how can I do this?




Coolpad Quattro 4G does in fact have a sim card to work, just needs the gsm part of phone unlocked.


It is possible to have your phone reprogrammed and use it with another carrier that uses CDMA technology. If you plan on using it with T-Mobile, unfortunately, you can't. T-Mobile has a GSM network and GSM phones use SIM cards, which the Coolpad Quattro 4G does not have.
