The O2-T-Mobile domestic roaming agreement dates back to the days when O2's predecessor Viag Interkom was constructing their GSM 1800 network. Viag simply wasn't able to build out its network as widely like Vodafone, T-Mobile and E+ did. So they looked to expand their domestic coverage by working together with an established provider.

Roaming is possible in certain areas only and as such only certain T-Mobile LACs (Local Area Codes) are opened up to O2 customers.
