Benefits of SIM Only
At the lower end of the contract range, £5 per month represents one of the cheapest monthly phone contracts on the market today which offers great value for those on a tight budget.
SIM only offers are generally 30 day contracts – this means that you are only tied to the contract for 30 days, which gives you the flexibility to terminate the contract quickly if you need to. On the other hand, you can continue to get the SIM only deal for as long as you like because the contract will continue to roll month by month until you choose to stop it.
A new phone is not required when taking out a SIM only contract because you will be able to insert the SIM card from a SIM only contract directly into your existing mobile phone. Sometimes it is necessary to unlock the phone before doing so, but this is a quick and simple process.
SIM only deals offer the best value for texts and inclusive minutes of any mobile phone tariffs with the flexibility of not being tied into a 12, 18 or 24 month contract unless you so choose.
