12
Months Piggybank Rollover
Sky Mobile runs entirely on O2's network, with its standout feature being Piggybank — unused data rolls over for later use, now extended to a 12-month window.
Plans
Often bundled with existing Sky services.
- Discount typically offered to existing Sky TV or broadband customers
- Combined billing available across Sky services
- SIM only and pay monthly options available
Coverage & 5G
Identical to O2's network, inherited fully.
- 4G and 5G coverage matches O2's own network exactly
- Does not appear separately in independent network rankings (uses O2's)
- O2's satellite feature does NOT extend to Sky Mobile customers
Roaming
A notable gap versus O2 directly.
- EU roaming charged daily via Roaming Passport Plus, not included free
- This differs from O2 itself, which includes EU roaming free as standard
- Worth weighing against the Piggybank and bundling benefits
Switching
Standard Ofcom-protected process.
- Text PAC to 65075 to keep your number when leaving
- Text INFO to 85075 to check contract terms first
- Check whether leaving affects any bundled Sky TV/broadband pricing
