In September, we reported that Orange and T-Mobile were offering roaming across their networks, so T-Mobile users would be able to call and text on the Orange network, and Orange users could do the same on the T-Mobile network.

T-Mobile explains that when you roam onto an Orange network, you will get access to the 2G network - mostly used for voice and texting, although it adds that you may some "basic, slow internet and data services."

Orange says in its FAQ that Orange users roaming onto T-Mobile will only get calls and texts, but that it is planning to include 3G roaming in 2011.

Sharing the Orange / T-Mobile signal is easy but you need to enable it.
