You do not need a contract to make a call
A working shortlist (2026)
| SIM | Ballpark | Network | Why it shows up here |
|---|---|---|---|
| Smarty | ~£4/mo | Three | Cheap, unlimited calls/texts on many plans, no nonsense |
| Asda Mobile | ~£5/mo | EE | EE coverage, supermarket-simple |
| Lebara | ~£5/mo | Vodafone | Minutes-heavy plans if you actually talk |
| giffgaff | ~£6/mo | O2 | Fine if you already live on O2 masts |
Prices move. Read the current plan page before you order. You will not use 15GB of TikTok data. A 1GB plan is usually theatre; it is there for the odd MMS or hotspot on a Punkt/Light Phone.
Number porting
Text PAC to 65075, give the code to the new SIM host, wait 1–2 working days. Your old SIM dies when the new one wakes up. Details on deals.
Dual SIM and travel
AGM M9 dual SIM is useful if you keep a foreign holiday SIM. Still buy 4G. VoLTE notes.
