The Benefits of SIM Only

The Benefits of SIM Only

Whether you’re after greater flexibility, or want to save money on your bill, moving to a SIM Only connection is a great option. SIM contracts offer cheaper line rental, and you can either upgrade, or change providers easily.

Below we take a look at some of the benefits of SIM Only, and the different options available.

SIM Only plans offers a range of SIM Only tariffs with a variety of data bundles and price points, letting you find a contract that suits your specific needs and budget.

iD Mobile


iD Mobile offers 12 and 24-month SIM Only deals, as well as rolling monthly options, all available with big-data bundles. Shorter contracts are perfect if you are unsure how much data you’re likely to use each month, or want to save some cash while waiting for an upcoming handset release. Longer SIM contracts are perfect if you’re happy with your current handset, and want the cheapest option.

Vodafone offers 12 and 24-month SIM Only deals. The cheapest option is a ‘Basic’ plan which simply provides calls, texts and data. Vodafone also offer Entertainment packages, with a choice of Spotify Premium, Amazon Prime or YouTube Premium.

Voxi offers 1 month rolling plans with big-data packages, great for those who are looking for additional flexibility or keeping their options open.

With a variety of network providers available, you can easily find the perfect price tariff for you, regardless of your data requirements. SIM Only contracts have lower costs compared to phone contracts, as you don’t have the price of a new handset included. You can also enjoy the flexibility of shorter agreements if you’d prefer not to be tied into a long-term commitment.


Roaming is the ability to use your phone in other countries. Choosing a SIM with a roaming plan lets you use your monthly data, texts and calls whilst travelling. This means you’ll still have data to share holidays snaps, use GPS to navigate your way around, and use your favourite translation apps.


iD Mobile offers EU Roaming in 50 destinations worldwide, so you can use your data, texts and minutes abroad, as though you were at home.

Customers of Vodafone are able to roam in 83 worldwide destinations which are split into 4 zones; A, B, C or D. Roaming in Zone A is included in all plans however, you’ll incur charges outside these destinations, with costs depending on the location and your plan. You can check your Roaming eligibility in the ‘My Vodafone’ app, as well as purchasing Roaming Passes for other zones.


Switching networks has never been easier, thanks to a new process which makes it both fast and user-friendly. Whether you want to keep your existing number, or cancel your old number with a new order, you can request this via text message, without having to speak to anyone.


If you’re looking to switch networks and keep your number, then you will need a PAC (Porting Authorisation Code). To receive this, simply text the word PAC to 65075, which is free to do. You’ll then receive a PAC from your current provider in a matter of minutes, which you can then use when placing a new online order with us. We’ll then contact your current provider to cancel your contract, and ensure your existing number is transferred to your new order.

If you want to switch networks and change your number, text the word STAC to 75075, and then use this code when placing your new order. Once you’ve placed your order, we’ll contact your current network to inform them you wish to cancel your old contract and number, and supply a new number with your order.

Alternatively, if you’re happy with your current provider you can select an upgrade deal, which will automatically carry forward your number without needing a PAC or STAC.
