Understand postcode validation, network availability, and the information confirmed before a UK order is paid.
4 minute read · Updated 2026-08-11Use a complete UK postcode
Aelixar normalises and validates the postcode supplied with the service address before creating an order.
Enter the full address accurately so fulfilment and any physical SIM delivery can proceed without avoidable delays.
- Full UK postcode
- Complete service address
- Server-side validation
Availability is not a street-level signal promise
UK network results describe provider network availability. Buildings, terrain, congestion, device bands, and indoor position can affect the service experienced at a specific location.
Review the network information together with device compatibility before choosing a plan.
- Network availability
- Device compatibility
- Local conditions
Review the complete GBP total
UK orders show the complete GBP amount before payment and do not use the USA CereTax location calculation.
A physical SIM can use a separate delivery address when required.
- GBP total before Stripe
- No USA tax step
- Separate delivery address
