Things to consider
When it comes to your phone, it's not always about getting the cheapest mobile plan. Here are some things to consider.
- Data Allowance
For most people, 15GB a month should be more than enough. However, depending on how you use your phone, you could need more.
Nowadays, many plans now come with unlimited data.
- Fair usage limits
Many providers advertise ‘unlimited calls, texts and data’ each month, but beware that limits do still apply.
However, in most cases, fair usage caps are way above consumer needs.
- 4G vs 5G
5G can reach speeds up to 10 times quicker than 4G.
5G SIM plans are getting more affordable every year, so is a great choice if you prioritise amazing download speeds.
Learn more - Contract length
Most billpay contracts last two years - so if you don’t want to commit to a period this long, consider a SIM-only deal or a pay-as-you-go plan instead, which are usually no contract SIMs.

SIM-Only FAQs
- Who has the best SIM-only plan?
The "best" SIM-only plan in Ireland depends on your individual needs. Popular mobile networks like Tesco Mobile, GoMo, Eir and Vodafone offer a range of SIM-only deals. Some excel in unlimited data and others in lower monthly costs or 5G coverage. bonkers.ie helps you compare plans quickly to find the one offering you the best value for your calls, texts and data allowance.
- Is it cheaper to have a SIM-only or contract?
Generally, a SIM-only deal is more cost-effective than a traditional phone contract and this is especially true if you already own a mobile phone. Contract plans often include the cost of a new smartphone and spreads that cost over a one-year or two-year term which typically leads to higher monthly payments. With SIM-only, you only pay for your mobile service so you save money each month.
- What are the disadvantages of SIM-only?
The main disadvantage of a SIM-only deal is that it does not include a new phone. This means you need to have a device already or buy one upfront. If your current phone is old or broken then a SIM-only plan might not be suitable unless you plan to purchase a new handset separately. However, this flexibility can be an advantage for many.
- What to look for in a SIM-only deal?
When choosing a SIM-only deal, consider your usage habits. Look at the data allowance you need. Do you require unlimited data or a smaller GB data plan? Check the included calls and texts and assess the network coverage in your area. Also, consider roaming allowances if you travel. Check if you need an eSim or regular sim and finally, compare the monthly price and contract length to ensure it offers the best value.
- Can I get a SIM-only deal and keep my number?
Yes, absolutely! When you switch to a new SIM-only deal, you can easily keep your existing mobile number. This process is called 'porting' and is straightforward. Your new mobile network provider will guide you through the steps to transfer your number to your new SIM card. This means no hassle for you when making the switch.

Cooling off period
You can cancel your broadband plan within 14 days from the day you receive your contract.
This is known as the cooling off period and gives you the right to change your mind without incurring any cancellation charges.
