Does iD Mobile increase its prices each year?

iD Mobile's Sim-only contracts are not hit by costly inflation-based mid-contract price increases. Before the end of the month, you will be able to check what the price to renew is. If it does increase or is too expensive, you can simply switch to a different network with no penalty.

For 24-month handset contracts, iD Mobile increases its prices each year by £1.50 each April/
