FAQ
Common questions
Can I get unlimited data for under £15?+
Yes — Talkmobile's £14.95/mo Unlimited plan and Smarty's £12-14 unlimited tariffs both fit under £15. Smarty caps speeds during congestion; Talkmobile doesn't.
Is £15/mo enough for 5G?+
Yes. Almost every UK MVNO now offers 5G at no extra charge. Vodafone-network MVNOs (Talkmobile, Lebara) have 5G in most cities. Three-network MVNOs (Smarty) have the largest 5G footprint by area.
