All You Can Eat and Feel At Home


Three's contract SIM deals offer a range of great benefits if you do not want to change your mobile phone. If you choose an Advanced Plan, you can use all of your data allowance as a personal hotspot in the UK, unless you have opted for one of their all-you-can-eat data plans, in which case you will be able to use up to 30GB as a personal hotspot.

All of the plans come with unlimited texts, which will allow you to send as many standard rate text messages as you like in the UK, while if you are on one of the Advanced Plans, you will be able to send up to 5,000 standard rate text messages to the UK each month from any Feel At Home destination.

Feel At Home is available in 60 destinations, from Spain to New Zealand, and also allows you to use your data allowance, text and make calls to the UK from abroad at no extra cost. Take advantage of 4G at no extra cost if you have a 4G phone and are in a 4G coverage area, while if you run out of data part way through the month, you can buy more in your My3 account.

Make sure you never spend more than you planned thanks to their fixed data allowances and usage alerts for minutes and data, while if you do run out of minutes, you can block outgoing calls. You can also block calls and texts to numbers which always fall out of your allowance.
