After the UK left the EU, most Brits can't use their mobile plans in Europe without extra charges. A £45 spending cap on UK mobile plans has also been dropped, so you could get a big bill by mistake.

The risk of a big bill is even higher if you travel outside the EU.

Some mobile providers charge up to £6 per megabyte of data and close to £3 a minute for calls. Streaming a song on Spotify uses 4MB of data, so you'd pay £24 just for one song.

Using Ubigi's eSIM can help you avoid big bills. You can get a free 500MB data plan and a 10% off coupon on your first purchase.

Whether you're in Europe or elsewhere, buying an eSIM before or during your trip helps you control your spending. For example, O2 customers in Japan pay £7.20 per MB or £9 per GB.

Ubigi offers a 1GB pass for £2.59 for three days, saving you £6.41. You can also buy a 10GB bundle for £10.36 for seven days, or an unlimited pass for £18.50 for a week.

An eSIM is a built-in SIM card in your device. It works like a traditional SIM but without the physical card.

After buying a Ubigi package, you'll get a QR code by email. Scan it on your device, sign up, and link your eSIM to monitor data and top up anytime.

An eSIM helps you save money and removes the hassle of physical SIMs. It's useful for travel, letting you switch networks easily and stay connected.
