The Best Sim Only Deals (Including 100GB for £15)
** Updated and refreshed 6th April **
Lots of people are looking for high data deals and unlimited minutes to keep in touch during these recent hard times and as a back up if your home broadband goes down with lots more pressure on it too. Might be worth taking a look at 30 day rolling deals so you get the extra data you want right now but without the commitment.
Sim only plans are great way to budget and get the best value without being tied up for 2 or even 3 years to a phone and airtime contract.
A really good way to use them is to buy your phone outright either refurbished or brand new at a discount (I have used Very and got 10% off (using Credit Account) a brand new already discounted iPhone) then pick the tariff that suits you the best.
If you know what you want and what your usage is, a 12 month sim only contract offers the best value for money but if you aren't sure or are a light user, a 30 day rolling contact maybe best for you.
I know a lot of people have sim only for their kids as you can cap the contract so they can't spend over the allowance but you have the security of knowing they have a phone in an emergency and you can always get hold of them.
A few of the best deals on different networks with examples below. I have put what network each provider uses as I know coverage varies on area so you don't have to go with O2 to get O2 coverage etc.

30 Day Contracts
Did you know? SMARTY is owned and runs on Three's mobile network.
a great tip is to haggle with your current provider I spent 45 minutes with O2 and went from 500mb for £9.99 a month to 6gb unlimited minutes and texts for a £10 a month so if you have the time it’s worth it
I think this was on MSE: for the best deal go through to cancellations as they have the ability to give the greatest discounts (apparently known internally as customer retentions)
Just got the Sky 2gb deal, you get free unlimited calls and texts if you’re a tv customer too, it’s a great deal.
Most people mainly want data these days with texting and calling not used as much as social media and WhatsApp etc
Sky might roll over data but their data allowance is quite low
I have EE everything everywhere - minutes texts and data £10 a month There are too many to look for at times
There's also a 'hidden' deal with Three at just £18 a month for 100GB data, unlimited calls & text. (12 months)
I've tried posting a deal today for the Samsung S10e at £28 p/m for 100GB data + free headphones worth £129, but the system has tried to add an affiliate code to the url so it doesn't work.
There are some exclusive partner channel deals that Three are not showing their website visitors but can be accessed using partner links.
Any ideas what to do please Tom
Same as the last comment I haggled with O2 been with them for years got 8gb unlimited everything for£10 brilliant
Wow. What a nice thread for sim card. Will have a look and choose the suitable one for me
This is a good deal to look at:

Thanks for sharing, just wondering, why must you be under 30 to use them? And if I use them now will they legit just turn around and go boom you've had your birthday we're gonna terminate your one month early or something like that?
I have just checked and found out they have now lifted the age ban.... 
Apparently it was because they thought only under 30’s would be drawn to the unlimited social media but their parent company Vodaphone have removed the age restriction now so I will edit and update 
I agree haggle with your current provider as I’ve had better deals every year on my sim only contract. Also when ringing them ensure you have details of a few other providers to make them think your moving providers!
So tempted with the voxi deal because they have free access to social media whice would be perfect for my teenage daughter only thing putting me off is you not able to speck to a real person it's all done online
Wow thank you for sharing this great deal but i prefer o2 better because the have proirity and it gives you alot of benifts
That's quite an effort. If only we could see more posts like this instead of packs of £1 chocolate bars that are pretty much always £1.
Re the Vodafone offer (100Gb for £15) - the link is sadly broken - it goes to Vodafone but displays an error 
.
ProfessorX it's Smarty that is 100Gb for £15 - Link working ok for me? >> https://smarty.co.uk/?
