These are temporary mauritian phone numbers or also called mauritian numbers. This means that they are only available for a short period of time. Some mauritian phone numbers last for several months, others only a few days.
Please do not use such a mauritian number for important text messages such as passwords, private text messages to friends or for phone verification on websites. Anyone could take over your account by reading the text messages of these mauritian phone numbers.
If you do not live in mauritius and still want to use a particular site or web that only accepts mauritian users, it is necessary to have a mauritian phone number to verify your account.
Most websites that require phone number verification have a limit on how often you can use a phone number. In this case it can happen that some of our mauritian phone numbers are blocked. But this is not a big problem. Just use one of our other mauritian phone numbers.
