We have compared all of the sim only unlimited mobile Internet offers and provided you with the best deals from Orange, Vodafone, O2, T-Mobile, 3 and Virgin Mobile.
Typically you will require a Smartphone or a relatively new phone model to be able to get the best experience from using your phone to browse the Internet. But once connected you can use the unlimited Internet on your phone to do most tasks such as checking and sending emails or surfing Facebook or your favourite sites. Ideally if you want to stay connected to the Internet it would be best to opt for an unlimited data package. You can pay extra to surf the web on your phone for short periods of time but these tend to be expensive and the data transfer offered is very low and expensive. By taking out a sim only plan with unlimited mobile Internet you don’t need to worry that you are going over your allotted time and accruing extra charges if you use the web a lot on your phone.
Unlimited mobile Internet is sometimes offered by the networks as part of a free add-on, such as the “bolt-on” scheme used by O2 so check for any add-on deals on offer.

Benefits of an unlimited mobile internet sim only contract
The sim only offers featured on Sim Only Deals are generally 30 day contracts and 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. Some other sim only contracts are for 12 months or even 18 months and the benefit of these is that you typically get a better deal if you commit for a longer period – these long-term sim only deals typically include more (or unlimited) texts, more inclusive minutes and better deals on mobile data and internet browsing, and may also be cheaper than shorter contracts.
You can continue to use your existing mobile phone if you take out a sim only contract, so you don’t have the expense of having to buy a new phone or the inconvenience of having to migrate your old data and learn how to use a new phone. If your phone was on a previous network you may have to have the phone unlocked, however, this is easy to do and simply involves the input of an alpha-numeric code into your handset to unlock it.
Even at the lowest price points per month, there is still a wide range of sim only deals to compare from all of the major mobile phone networks. Deals include O2 Simplicity sim only, Orange raccoon or dolphin sim only, Vodafone sim only, T-Mobile Solo sim only, 3 sim only and Virgin Mobile Liberty sim only. At the higher price point you can expect to see up to 1,000 free minutes and a combination of free texts, and/or free mobile Internet.
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 choose to be.
