What is SIM Only?

SIM Only is where you get a SIM-card and a plan from a network, without a mobile phone bundled into the equation. We know you have a lot of choice and plenty to compare when it comes to changing phone. It’s important to remember that not getting a new phone at all is also a choice you have option in the choice you make. 

Benefits of SIM Only 

SIM Only has become a very popular option in recently years. Maybe you’ve got the iPhone 11 and are looking at the iPhone 14. In days gone by, you might have upgraded, but today we all need to make our money go as far as possible. That might mean you need to hold onto that iPhone 11 for a year longer than you would have before.

The good news is that phone quality is at an all-time high and phone technology isn’t developing at quite the rapid rate it was a few years ago. All of this means that a little bit more time in between upgrades doesn’t mean you get left behind in terms of technology.

Thanks to SIM Only, it also means you don’t have to get left behind in terms of monthly value.

When you find a great value bill pay SIM Only deal, you’re getting the best of both worlds. These plans often offer the same calls, text, data, and roaming allowances as the most expensive plans a network offers. But with the price of the phone stripped out, it can get very appetising.

Better still, if you wait for a particularly impressive SIM Only deal, you can save a small fortune. Given how things are pretty tight right now, we’ve created an eye-catching SIM Only offer available to everyone in Ireland. 

Three’s Bill Pay SIM Only Deal

We have a very exciting SIM Only deal available to everyone shopping around for SIM Only offers right now. Normally, we offer a €35 bill pay SIM Only plan on a 30-day rolling contract. For this, you’ll get our famous All You Can Eat Data, Unlimited calls and texts, 60 international minutes and texts and 5G included for free along with 32GB of EU roaming data.

Note, the unlimited calls, and texts are subject to a fair usage policy of 3000 minutes in the Republic of Ireland and 3000 texts, but you’d be doing really well to get through that much! All You Can Eat Data is similar. It’s more or less unlimited data. You can check out the full terms too.

Right now, you can get this same SIM Only plan on a new 12-month contract and save 50% on the first 6 months. You’ll still get All You Can Eat Data, Unlimited calls and texts, 60 international minutes and texts, 5G included for free and 32GB of EU roaming data, but for just €17.50 per month for the first 6 months.

The plan then returns to €35 per month. The big difference here’s that by committing to the plan for 12 months, in the first year you spend just €315 on your base phone plan instead of €420. That’s a massive saving of €105 in the first year.

There are lots of other reasons to be excited about joining Three too.

After ten months on the 12-month SIM Only plan, you can upgrade just like any other Three Bill Pay customer.
