Set up before you fly
Buy in the Saily app and install your QR code at home. Your plan activates automatically when you first connect to a local tower in United Kingdom.
Keep your existing number
Saily runs as a second line alongside your home SIM. Your usual number stays active for calls and texts — Saily handles data only.
Real-time data usage
Track exactly how much data you've used at any time in the Saily app, so you never get caught short before your next refill.
Travel beyond United Kingdom
If your United Kingdom trip is part of a wider journey, Saily covers many other destinations from the same app — manage everything in one place.
Flexible up to 365 days
Saily United Kingdom plans run up to 365 days from first use. Buy in advance so you're ready the moment you land.
Which Saily plan should you pick?
For a short city break of 3–6 days, the cheapest plan at $4.49will cover Maps, WhatsApp and casual browsing. If you’re spending one to two weeks travelling around United Kingdom, step up to a mid-tier plan — usually the strongest value on a per-GB basis in Saily’s United Kingdom lineup.
If you plan to work remotely, stream video daily, or use your phone as a hotspot, lean towards a larger bundle. The unlimited plans cost a premium but make sense for heavy users who don’t want to track usage.
One thing to note: Saily United Kingdomplans are data-only. You won’t get a local number, but your existing SIM handles calls and texts as normal — messages, WhatsApp and FaceTime all work over data.
