Holidaymakers issued urgent warning about sky-high mobile charges when travelling outside EU

Holidaymakers have been issued a firm warning regarding the potential of escalating mobile charges when travelling outside the EU zone. The celebrated Money Saving Expert voiced concerns in its most recent newsletter, indicating that certain providers are charging customers fees upward of £8 per day for nominal data use.

Additionally, unaware tourists could face extra costs by using their add-ons, such as streaming TV on their data plans whilst overseas. To avert these steep mobile bills, holidaymakers are being urged to consider an economical international eSim.

These digital sims grant all the typical benefits of a conventional physical sim card and function by temporarily adjusting your phone's settings to link you to a foreign provider, thus providing a separate data allowance. Esteemed personal finance expert Martin Lewis has even revealed his own positive encounters with eSims during his European trips.

Sharing his experience, he said: "As I was going out of Europe for just under 10 days, I picked a one-month 10GB eSim for £18. My own network charges well over £6 a day for a 500MB daily data limit."

Admitting his initial scepticism about using an eSim due to possible signal strength and messaging issues, he told the Mirror: "I was a touch trepidatious about whether it would work, if the signal would be good (as it could only connect to two networks rather than all) and how it would work with messaging."

Yet he was immensely pleased with how straightforward it was to set up an eSim at the airport, mentioning that it took a scant six minutes following the provided instructions. He shared his thoughts on the experience by saying: "Once I was abroad, after a little confusion that there was no homepage indication that a different Sim was being used (I found myself flipping to the eSim app, waiting to see if it was using up megabytes - after a couple of minutes it started to register), it was easy.

"I got a strong 4G signal virtually everywhere, and used the internet with the freedom and speed of home. The 10GB limit lasting my whole time away smacks the bottom of a 500MB daily limit, as you don't need to worry about busting it with one download."

He summed up the process as "very simple" and appreciated the ease with which he could revert to his regular sim card within seconds. He advised those interested in an eSim to ensure their iPhone or Android is compatible by checking with their phone manufacturer or eSim provider.
