For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for the UK is $5.59 on O2, Vodafone and 3. That is about 53% less than the major eSIM brands charge for 10GB over 30 days (around $19.00, checked September 2026). Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
