30-day rolling SIM only plans
A 30-day rolling SIM only plan runs a month at a time: you can usually leave with 30 days’ notice and no exit fee. The trade-off is that the price is not fixed for a term, so the network can change it with notice.
12 current offers from Lebara, 1pMobile, iD Mobile, O2, Your Co-op, Mozillion, as each seller states them, in order of monthly price.
What rolling means
There is no minimum term beyond the month you are in. That suits a short stay, a first month in the UK, or trying a network before committing.
The price can move
A rolling plan has no fixed-term price to protect. If the network raises it, it must tell you first, and you can leave without a fee.
