Why FlexiFone

What you actually get.

No approved-app lists, no single-network lock-in, and no contract to sit out.

 

01
An allowance, not a pot. Your data reloads every 30 days for as long as you keep the plan. Prepaid SIMs sell you a fixed amount with an expiry date, and whatever’s left when it lapses is gone.
02
You choose the networks. Block your primary network from your account portal so the SIM only uses the other three. We’re the only UK multi-network provider that lets you decide.
03
Nothing is off-limits. No approved-app lists, no streaming or social blocks, no traffic de-prioritisation, and a hotspot that works on every plan.
04
£0.30 a gigabyte at the top tier. £45 a year for 5GB a month, £365 for 100GB. We publish the per-gigabyte rate on every plan so you can check the maths yourself.

All four networks.From £3.75 a month.

Nothing to remember to switch off. Annual plans work out at £3.75/mo, or stay on 30-day rolling and change or leave whenever you like.
