Pay Monthly SIM Only Plans

Note: This is a historic webpage and may contain out of date info. Please check the Price Guide for your plan for up to date info.

Our SIM Only plans come with a set of allowances of text, voice and data units, unless you are on a SIM Only mobile broadband plan, in which case your monthly allowance will only contain data units. These units automatically convert on use into text messages, megabytes of data and voice minutes, as appropriate. How many units of each you have will depend on which price plan is chosen. On our Advanced plans and mobile broadband plans, these units can be used in the UK and in all our Go Roam Around the World destinations (including our 49 Go Roam in Europe destinations) while on our Essential plans, these units can only be used in the UK or our Go Roam in Europe destinations.

All of our SIM Only plans are available on a minimum term contract – we currently offer minimum terms of 1, 12 or 24 months. To end your contract, you’ll need to give us 30 days’ notice.

If you are on a SIM Only voice plan, you may only use your SIM in a 3G or 4G mobile.

If you are on a SIM Only mobile broadband plan, for use in a dongle, mobile wifi device or tablet, and are on one of our mobile broadband plans, and you use your SIM in a 3G or 4G phone, please note that this may not work as expected as it is being used in a device category for which it was not designed.

Inclusive Allowances – Your first month's allowance and charge will depend on when in the month you join Three. Whenever that is, you can start using your allowance straight away. We'll work out an appropriate allowance and charge to take you to the end of the first month. After that, you will receive the full inclusive allowance each month and will pay your standard monthly package cost.

Voice - On our Advanced Plans (including all SIM Only voice contracts entered into from 15 July 2014 onwards), inclusive calls are from the UK or our Go Roam destinations to UK landlines beginning 01, 02, 03 and UK mobiles. Additionally, calls made between Go Roam in Europe destinations will come out of your inclusive allowance. On our Essential plans, inclusive calls are only from the UK to UK landlines beginning 01, 02, 03 and UK mobiles, and do not include calls from our Go Roam destinations unless made between our Go Roam in Europe destinations. On all our plans, Personal Numbers (070) and Service calls (beginning 084, 085, 09 and 118) are excluded from bundle. Service calls will incur both an Access Charge (set by us, at 45pence per minute, including VAT) and a Service Charge (set by the company you’re calling – they’ll tell you this). For pricing information go to Three Price Checker or Three Price Guide. Additionally, on our Essential plans, calls to Three Customer Services will come out of your inclusive minutes – if none are available, you’ll be charged our standard out of allowance rate for these calls. On our Advanced plans, these calls are free.

Texts - On our Advanced plans, inclusive texts are texts sent in the UK or any of our Go Roam destinations to standard UK mobiles. Additionally, texts sent between Go Roam in Europe destinations will also come out of your inclusive allowance. On our Essential plans, inclusive texts are texts sent in the UK or back to the UK from a Go Roam in Europe destination or between Go Roam in Europe destinations only. All of our new SIM Only plans include All-you-can-eat texts. On our Advanced plans, this includes an allowance of 5,000 texts to be sent from a Go Roam Around the World destination each month back to the UK. There is no limit as to how many texts may be sent from an all-you-can-eat data allowance in Go Roam in Europe destinations.

Data – On our Advanced plans, your data is for use in the UK and any of our over 160 Go Roam destinations only. On our Essential plans, it is for use in the UK and our 49 Go Roam in Europe destinations only. A fair use limit for data use in our Go Roam destinations of 12GB – use over this but within your inclusive allowance in our Go Roam in Europe destinations will be subject to a surcharge for continued use of up to 0.50p per MB except if you are roaming in the following countries in which case it will be 0.41p/MB: Aland Islands, French Guiana, Guadeloupe, Martinique, Mayotte, Reunion, Norway, Switzerland, Gibraltar, Iceland, Liechtenstein. Data use over 12GB per month in other Go Roam destinations (non-Europe) will be blocked. If you reach your monthly limit of inclusive data you’ll be charged your standard rate to continue using the internet. Advanced Plan customers who have an All-you-can-eat data package may use their phone as a Personal Hotspot (up to 30GB) in all Go Roam destinations worldwide. In addition, contract customers who have purchased a Data Travel Pass can use their phone as a Personal Hotspot in all Go Roam destinations and Pay As You Go customers can use their cash credit at 1p/MB to create a Personal Hotspot in our Go Roam in Europe destinations. Using your inclusive allowance data to create a Personal Hotspot is not allowed on our Essential Plans. Please check your Price Guide for further details. For general information - see here
