Olimit Tips & Tricks

Do I need unlimited data SIM Only deal?

Unlimited data SIMs offer complete freedom, but they often come at a higher monthly cost. Before you commit, think about your usage. The average UK mobile user only uses around 10GB of data per month, so if you mainly browse, message, and stream occasionally, a smaller data plan might save you money.

However, if you’re always streaming Netflix, gaming on the go, using your phone as a hotspot, or working remotely, an unlimited data plan could be the hassle-free option you need. At Olimit, we help you compare unlimited and capped SIM Only deals, so you can find the best match for your data habits and budget.

Can I use my unlimited data SIM abroad?

It depends on the network. Look for in the deal listings below — it will show you how much roaming data is included and which countries are covered.

Most UK providers include EU roaming with unlimited data SIMs, but your usage abroad is usually capped — often between 12GB and 35GB per month. Some networks also charge extra for roaming outside the EU, like in the USA, Australia, or Asia.

Before you travel, always check your network’s roaming fair usage policy and whether your destination is included. At Olimit, we make it easy to compare unlimited SIM Only deals with roaming included, so you can stay connected abroad without unexpected charges.
