Want Challenger mobile but can't find your phone on this page?

In order to use Challenger mobile your phone needs to support internet calls. If you aren't sure if your phone does, contact your handset provider and ask "Does my phone support internet calls (via the SIP protocol)?"

If the answer is YES, great! Please remember to let us know

Otherwise, you can register interest now and we'll let you know as soon as we have a new release!
