Cheapest SIM Card Plans with Unlimited Data

 

 

Want to know which networks offer the lowest prices for unlimited data with their SIM Only deals?

 

Look no further, we’ve got you covered!

 

The cheapest unlimited SIM card plans start from just £16 a month and include unlimited calls and SMS.

 

If you’re looking for a rolling 30 day SIM Only deal then it’s Smarty that takes top spot with their 20% off usual price unlimited data SIM.

 

For the same £16 a month you can also enjoy unlimited data, calls and texts on iD Mobile 12 months contract and claim £48 cashback.

Smarty and iD Mobile both operate on top of the Three network, you can check the signal strength in your area before ordering using Ofcom’s coverage checker, here.

 

 

What’s the difference between these two networks?

 

Well, the biggest one is the amount of data you can use whilst roaming in the EU!

 

Smarty allows you 12GB of your unlimited data with no charges to access it whilst iD Mobile offers you more than double at 30GB, again with no fees.

 

The next cheapest network offering unlimited SIM Only deals is unsurprisingly Three, they offer unlimited everything at £18 on a 24 month contract and £19 on a 12 month plan.

You can enjoy unlimited data, calls and text as well as 100 international free minutes to 42 countries as well as use 30GB of your data in the EU and India free of charge.

Not wanting to go over the £30 a month mark, the final unlimited SIM’s are on Vodafone and start at £26 a month on a 24 month agreement and £27 on a 12 months contract.

 

There are some nice incentives being offered with both deals, you can enjoy £130 automatic cashback with the 24 month plan which is automatically paid into your bank, or claim back £147 with the 12 month plan.

 

 

 

Vodafone SIM Only Unlimited Data Deals

 

 

 

The snag is that both are on Vodafone’s ‘Unlimited Lite’ plan which restricts data speeds to 2Mbps.
