9 Reasons You’ll Be Happy With A SIM Only Contract
Keep your existing smartphone:
This is where the money saving is most potent. If you have an existing mobile phone then you are primed to take advantage of SIM Only contract deals.
Short-term contracts:
Choose from a 1 or a 12-month contract. The longer the term, the better the value. For more flexibility go for a 1-month rolling contract.
Keep your phone number:
It’s so simple and hassle free with little to no downtime. You can keep your number by following our guide on making the switch from one network to another.
Lower prices, better allowances:
When compared with a pay monthly mobile tariff, SIM Only packs in more minutes, data and texts for almost half the price.
Make calls to any UK network:
No matter which network you choose, they will all provide you with minutes that allow you to call other mobile networks that your friends and family might be on.
No need to top up like PAYG SIM cards:
The great advantage over pay as you go is that you won’t have to worry about running out credit and tediously top up every time you are low.
Tailored tariffs for iPhone and BlackBerry:
All the main networks now offer tailored packages for these phones and you can compare them on all on SIMOnlyContracts.co.uk.
Flexible tariffs designed for you:
There are now a very wide range of SIM Only deals to choose from whether you want something cheap and cheerful or a buffet style plan.
