Sky Mobile unlimited data sims

An unlimited data plan makes sense if you regularly stream video, tether other devices or rely on your phone for everything without wi-fi.

If you typically use under 20GB a month, a capped Sky Mobile plan is usually cheaper — and Sky's Piggybank rollover means you rarely waste a smaller allowance anyway.

Sky Mobile's unlimited plans give you genuinely unlimited data over O2's network without a hard cap on how much you can use.

As with all networks, a fair-use policy applies to discourage commercial misuse, but normal personal use including heavy streaming won't see you throttled or charged extra.
