Especially for older phones or for those who don’t need mobile data, for £5 a month you’ll get UNLIMITED calls and texts, but there is no data allowance. *Minimum top up will be £10, which will last for 60 days.
You can still access data at the price of £1 per day per 50MB. This will be taken from the available credit on your sim card, so we recommend that you turn off Mobile Data if you are using a smartphone.
You will of course still be able to access your own home or work WiFi as well as free O2 WiFi from hotspots around the UK.
