Traveller notes

Airport pickup
Heathrow, Gatwick and Manchester all activate at the gate on EE, O2 or Vodafone. Students: this is your bridge until a local SIM arrives.
Hotspot and calls
Allowed on most plans. Useful for the first week before student halls Wi-Fi is set up.
Where the network is weak
Cities are strong. The Scottish Highlands, rural Wales and Cornwall drop on Three-based plans; EE holds up best.
Local SIM alternative
Giffgaff, Lebara or Voxi pay-as-you-go SIMs are far cheaper for anything over two weeks and give you a UK number for bank and NHS sign-ups. Order one before you fly and use the eSIM as a bridge.

Paying from India or Pakistan

Providers take Visa and Mastercard. Indian debit cards need international use enabled and carry a 2 to 3.5% forex markup; UPI and RuPay-only cards are not accepted. Pakistani cards need international transactions enabled at the bank, sit under the annual dollar limit, and carry a 3 to 4% markup; JazzCash and Easypaisa are not accepted. Apple Pay and Google Pay work where your card does.

Install it on Wi-Fi before you fly and keep it switched off until you land. Heathrow, Gatwick and Manchester all activate at the gate on EE, O2 or Vodafone. Students: this is your bridge until a local SIM arrives.
