Choosing your SIM Only
BT SIM only deals are extremely competitive and always offer great value to both new and existing customers. There are weekly offers available that are exclusive to customers buying online. This can include FREE Amazon or iTunes vouchers, extra data or discounted monthly prices.
There are two sets of 3 simple deals to choose from. One for existing customers (these start at £5 per month) and one for new customers (starting at £10 per month). If you are not an existing customer then you will be paying £5 more per month for the same SIM plan.
Want value for money?
In addition to the weekly promotions on SIM Only deals, BT offers great added value with no charge for 4G data, FREE tethering within your allowance and FREE unlimited access to over 5 million BT WiFi hotspots.
One of the other key benefits of a BT SIM is that you can cap your monthly spend so that you won't get any unexpected bills.
What about Internet?
All BT SIM Only plans come with data designed to suit your needs. The minimum amount is 500MB on Plan 1 (the cheapest SIM at £5 for existing customers) which is only suitable if you won't be using the Internet a lot or able to use WiFi most of the time.
Plans 2 and 3 come with 2GB and 15GB, respectively. 2GB is about enough for most moderate users and 15GB will be sufficient for most heavy data users. Both these plans are reasonably priced for existing customers at £10 and £20.
Save more with a Family SIM. With this fantastic SIM plan, the more additional SIMs you add the lower the cost will be. This offer is not just limited to family members though as you can also invite your friends too! It's also great if you have more than one device that needs data as you can stream and download more at a lower cost plus you get one bill for all SIMs.
An example saving for a Family plan of 4 SIMs is this:
Original price for SIM 1 = £15
SIM 2 = £8
SIM 3 = £7
SIM 4 = £6
Your overall saving would be £24 a month or £288 a year!
SIM Only Contracts' top tip:
Our editor says:
With great value for money if you are an BT customer already and additional benefits like free tethering. It isn't promoted much but you can also watch BT Sport on your mobile with their special app for mobile customers.
I like: Great value for existing BT Broadband customers. Fantastic weekly offers including up to £80 in Amazon or iTunes Gift Vouchers.
I don’t like: Given that BT broadband customers get a £5 discount on their SIM Only deals, it's highly likely that you will be able to get a better, cheaper plan on another network if you are not a BT customer already/.
