Each number line has its own rules, set by the mobile network. A call the line doesn't allow fails however your phone is set up, so check your line below.

On every line

• Dial every number in full: +, the country code, then the number, even for a local call. Leave out a leading 0 after the country code.
• Calls and texts use the minutes and texts in your plan.
• A text holds 160 characters, or 70 if it contains emoji or non-Latin characters. A longer text is sent in two or more parts, and each part may count as a text.
• Apps that call and message over data, such as WhatsApp, work on any plan where those apps are available.

Line by line

Global+

• A US number (+1) that works in the countries listed on the plan.
• It calls and texts numbers in other countries, not only local or US numbers. Those calls use your plan's normal minutes: there is no separate allowance for international calls.
• It sends texts to, and receives them from, ordinary mobile numbers abroad (for example in Ghana and mainland China).
• US toll-free numbers should work while you're in the US, though some may be restricted. Toll-free, bank, airline and other restricted numbers may not work while you're roaming. Australian 1300 and 1800 numbers, short codes and premium-rate numbers can't be called: use the service's ordinary number instead.
• No call forwarding and no voicemail.
• In some countries, outgoing calls may not be available. If calls won't connect, use an app over data and tell us.
• In Turkey, use for more than 91 days is restricted by local rules.
