Is Wiseclearwise affiliated with any mobile network?+
No — completely independent. Wiseclearwise has no commercial, financial or operational relationship with O2, Three, EE, Vodafone, Tesco Mobile, Sky Mobile, Lebara, iD Mobile, Giffgaff, or any UK network. We do not earn referral fees or commissions from any operator. Our 0808 280 6350 free line reaches our own team — never any network's helpline.
What changed at Sky Mobile in 2024?+
Two significant changes: (1) Piggybank maximum storage reduced from 3 years to 12 months in April 2024. (2) Data-free Sky TV streaming removed for new customers in 2024. Any Sky Mobile review or guide written before 2024 may describe these features as they previously were — not as they currently are. Always verify at sky.com/shop/mobile.
Which of the 9 networks is fastest for 5G?+
Three holds 140MHz of 5G spectrum — more than any UK rival. Opensignal January 2026 rated Three #1 for 5G Download Experience at approximately 187Mbps median. EE leads for widest 5G geographic coverage at 87%+ of UK population across 500+ towns. Speed and coverage are different metrics.
Which networks include free EU roaming on all plans?+
O2 (all standard plans, 25GB, 48 destinations). Tesco Mobile (most plans, 25GB). Lebara (all plans, 30GB EU + India). iD Mobile (eligible plans, 50 destinations including USA/Canada/Australia). Three (Value and Complete only). EE (Essentials Plus+). Vodafone (Xtra only). Sky Mobile and Giffgaff vary by plan.
What is giffgaff and how is it different?+
Giffgaff is an O2 MVNO operating a community model — members help each other on forums, earning payback (cash) for contributions. No fixed contracts — all plans are monthly goodybags that you can pause or cancel anytime. No annual price rises on rolling goodybags. Popular for transparency and flexibility.
What is the VodafoneThree merger?+
Three UK and Vodafone UK merged into VodafoneThree, completing 31 May 2025. Both brands continue operating completely separately — different plans, pricing, apps and customer service. £11bn network investment committed targeting 99% 5G coverage by 2030. No forced migration for customers on either brand.
How do I keep my number when switching?+
Text PAC to 65075 — free, within 60 seconds, from any UK network. Give the 9-character code to your new network at sign-up. Number transfers within one working day. Old contract cancels automatically on port completion. Never cancel your old contract separately beforehand.
What is the pounds-and-pence rule?+
Since 17 January 2025, Ofcom requires all UK mobile networks to disclose planned annual mid-contract price rises upfront in exact pounds and pence — not as a vague CPI or RPI formula. You must know the precise monthly increase before signing any contract.
