Inclusive roaming in 52 locations
All customers on iD Mobile SIM only and mobile phone plans allow you to use your UK monthly allowances of data, calls and texts in 52 locations in Europe and beyond for no extra charge.
iD Mobile allows customers to rollover unused data from one to another for free, so you've got a second chance to use it. Any data that's unused from last month is rolled over automatically.
Customers can set spending limits for monthly bills for the UK and overseas, to avoid being hit with unexpected charges.
A buffer of up to £5 extra is available, however, which they can use when they need an extra allowance.
Caps can be adjusted with the iD Mobile app.
Launched in 2015, iD Mobile promised consumers “capped plans for the lowest price on the market” and roaming plans that it claims “cover more European countries than anyone else”.
It uses Three's network to ensure customers get nationwide coverage and fast speeds.
iD Mobile doesn't offer a mid-contract handset upgrade scheme that's comparable to Tesco Mobile's Anytime Upgrade Flex or O2 Refresh. However, customers who renew contracts are often able to get a new phone before their existing contract ends.
