Everything about calling Three from abroad
Who Three is, and what its two free numbers are for
Three is a UK mobile network. The header of its website reads Order by phone: 0800 033 8006, on its home page, its broadband page and its Contact us page alike. Its business site carries a second number, 0808 258 0333, which the Three Business contact page gives for sales and upgrades: buying, upgrading or adding a line. Both are numbers for buying from Three. Help with an existing personal account has its own lines on Three's Contact us page, including +44 7782 333 333 from abroad at standard roaming rates, and Live Chat.
Why you might ring Three's order line from abroad
The usual reasons to call from outside the UK are getting ready to arrive, with a Three plan sorted before a move or a return, or arranging lines for a UK team on 0808 258 0333. Either way the call starts from a foreign phone, and a UK number may not exist yet.
Why a UK 0800 or 0808 number is awkward from a foreign line
0800 and 0808 numbers are free to call inside the UK, and that rule stops at the border. From a foreign SIM or landline, the call may not connect, depending on your operator. Three says nothing about the cost of either number from abroad; the only lines it prices for callers abroad are its customer support numbers, at standard roaming rates.
What Losali does with these numbers
Losali is an independent dialler that runs in a web browser. Your call travels over the internet and Losali's telecom carrier connects it to the UK number, so your foreign network only carries data. There is no app to install and no UK SIM to buy, which helps when you are calling to get your first one.
- Know what you want to order: a phone on a plan, a SIM only plan, or broadband.
- For broadband, have the UK address where it should be installed.
- For business lines, know how many lines you need and whether any are upgrades.
- Three Business sales answers Monday to Friday, 9am to 6pm UK time, and is closed at weekends.
