Which one is right for you
These aren’t quite the same product. One is a subscription; the other is prepaid connectivity sold by the gigabyte.
Choose FlexiFone if
You want a recurring allowance at subscription prices
- You want an allowance that reloads every 30 days
- You want 60GB across a year without paying prepaid rates for it
- You need roaming, tethering and network controls as standard
- You want a 30-day rolling option rather than committing upfront
Choose AnywhereSIM if
You want prepaid connectivity, or a specialist device SIM
- You want a one-off prepaid SIM with no account to manage
- You only need 30 days or 3 months, not a full year
- You'd rather pay once for a fixed pot than hold a subscription
- You want pay-as-you-go voice rates on a rarely-used device

The difference that matters
A pot with a deadline, or an allowance that reloads
AnywhereSIM’s data-only SIMs give you a fixed amount of data to use inside a set window — 30 days, 3 months, 6 months or 12 months. When the window closes, anything left goes with it.
FlexiFone works as a subscription. The £45 annual plan gives you 5GB, and then another 5GB thirty days later, twelve times over. A quiet month doesn’t cost you anything, and a heavy one doesn’t eat into next month.
That structural difference is also why the prices look so far apart. Prepaid connectivity sold by the gigabyte is priced differently from a consumer subscription — it isn’t that one company is eight times greedier than the other.
What you actually get.
The same 60GB across a year, at subscription pricing rather than prepaid rates.
It reloads. 5GB every 30 days on the £45 annual plan, twelve times over. Nothing expires unused because you had a quiet month.
Roaming and tethering as standard. Free across the EU and EEA, roam like home in 170+ countries, unrestricted hotspot on every plan — not dependent on which product you bought.
You control the networks. Allow or block any of EE, O2, Vodafone or Three from your account portal.
Rolling if you want it. 30-day plans from £8/mo, so you can leave after a month. Their shop products commit you to the full validity period upfront.
Pricing compared
What a year actually costs
The same 60GB, twelve months
Same data, same twelve months, £315 apart. Worth saying plainly: these are different kinds of product, and prepaid data sold by the gigabyte carries different pricing. But if what you need is 60GB over a year on all four networks, the cheaper one is the cheaper one.
