Solo Sim Card
The Solo sim card by T Mobile is available at £10 a month. At £10, you can get 150 minutes to any network and 300 texts to any network as well. Solo sim card is a 30-day contract deal so you are not attached for 18 months or 24 months.
In fact, you can cancel at anytime as long as you give a 30-day notice in advance. This is suitable for everyone. If you love the freedom to have your mobile deal in control, go for Solo sim deal. Besides, if you have an existing phone, why get another one when you can just get a Solo sim deal for it? Getting a contract with free mobile phone is a total waste unless if you need a new phone.
