SIM only deals with no mid-contract price rise

Networks publish their price rises in the contract terms: the amount, and the date it takes effect. Our feed carries that schedule for every deal, and we already show it on every deal card across Switchity. This page goes one step further and lists only the deals with nothing scheduled.

Two caveats keep this honest. First, rise-free describes the deals on sale today; a network can add a rise to the deals it sells next year. Second, Sky Mobile is a special case. Its contracts schedule no fixed rise, but the terms say the price could change with notice, so we do not count it as truly rise-free.

Most plans from the big networks schedule a rise every April. Since Ofcom's January 2025 rules the amount must be stated in pounds and pence before you sign, which is clearer, but there is a catch. Because you agreed to the rise at the point of sale, it does not trigger a penalty-free exit. The clean way out is to never agree to one, and that is what this page is for. The rises are not trivial either: a flat amount added to a small bill is a big percentage, so the cheapest plans are hit hardest. Our guide to SIM only mid-contract price rises has the rules, the per network amounts and your exit rights in full.

Skipping the rise does not mean settling for a weaker signal. Most rise-free networks are smaller brands running on the same masts as the networks that raise prices. iD Mobile and SMARTY use Three's network, giffgaff runs on O2, VOXI and Talkmobile use Vodafone, and spusu uses EE. Coverage on the high street brand and its rise-free lodger is the same; the difference is the April letter. Use the coverage checker above to confirm the host network is strong at your postcode before you commit, then filter this page by network to shortlist deals on that host.

Every rolling plan qualifies for this page, because a plan with no minimum term has nothing to schedule a rise inside. But rolling certainty is the weaker kind: the network can change the ongoing price with notice, and your protection is leaving before the change starts. A fixed term deal with no scheduled rise is the stronger promise, since the price is locked for the whole term and the network cannot move it. So decide what you are buying. If you want the exit, a 30 day SIM gives you that and the flat price along the way. If you want a bill that cannot move for a year or two, pick a 12 or 24 month deal from this page.

Three things keep the promise honest. First, the lock ends with the minimum term: once a contract rolls on, any network can change the price with 30 days' notice, so set a reminder for the end date. Second, a rising deal with a deep introductory discount can occasionally cost less over the term than a rise-free rival, so compare what you would pay across the full term, not just the first month. Third, allowances and perks vary between terms and networks like everything else in the market; the absence of a rise is one column in the decision, not the whole answer.
