About Us

On Top Up was set up in 2019 to provide a simple way to add top up credit to any mobile phone on any network. For example, if you have 3 children with Pay As You Go phones on different mobile networks, to add top ups previously you would need to go to each network website in turn, log into the relevant account and go through the steps to buy more credit. With On Top Up, you have 1 account, and once logged in, you can add credit to any phone with just a couple of clicks.

On Top Up works across many of the world's mobile phone networks, so if you are travelling and using different sim cards, you can always top up your credit via your one On Top Up account.

On Top Up is wholly owned by Surestream Digital, based in London, UK. If you have any questions regarding our service, please contact us.
