The results of the test are grouped by mobile network operators. These network operators use several different brand names to interact/ communicate with end users. In case of resellers and “mobile virtual network operators” the end user does not have a contract with the network operator, but with a service provider instead.
RTR provides an overview
of brand names, underlying service providers (contractoing party of the end user) and underlying network operators.
Brand names may change frequently. We try to keep the information as up-to-date as possible and appreciate any information / corrections sent to firstname.lastname@example.org
