Your Safety BufferClose Article
When you joined Tesco Mobile you had the option to add a safety buffer or not. A safety buffer is a cap on your monthly bill, so it'll never be higher than you expect.
Manage your safety buffer
If you have multiple numbers on one account, each number is treated separately, so you’ll need to have a safety buffer for each one. Only the bill payer, is able to change the safety buffers of others on the account.
No safety buffer?
Don’t worry if you didn’t chose a safety buffer when you joined or if you choose to remove your safety buffer, as your usage will still be protected by the high usage limit. Find out your high usage limit.
You can increase your high usage limit by calling Customer Care on 4455 from your Tesco Mobile phone.
