The eSIM Europe Unlimited Data didn’t work in Serbia — while it worked fine in other EU countries (Switzerland, Austria, and Germany).

I opened a ticket a week ago and still haven’t received any help.

Avoid this company’s SIMs. If they fail, good luck getting help — you’ll end up buying a new one somewhere else.

Ivoused in Serbia 🇷🇸

Next I'd think twice before I use the cheapest option. I activated my SIM but wasn't able to use it. I tried everything that came to my mind for 2-3 hours and couldn't make it work.
The support couldn't provide me with a solution either, so I was without data all day. At the end of my trip, on my way back to Bulgaria, I gave it another try, just before I crossed the border, and it suddenly worked.
I got a message from the support on the next day with a suggestion and a possible solution, but it was too late, 'cause I was in Serbia only for a few hours and that's when I needed my data.
I'm definitely not happy with the experience.

Frequently Asked Questions

How many travel eSIM brands (providers) are available for use in Serbia, and how many prepaid data plans are there?

There are over 110 travel eSIM providers and over 3700 prepaid data plans available for use in Serbia, offering a wide variety of options to meet travelers’ needs.

Are there any unlimited data eSIM plans available for Serbia?

Yes, there are unlimited data eSIM plans that cover Serbia. A number of providers offer such plans, most of which allow tethering and include some speed throttling or imposed limits. For example, Firsty offers a 1‑day unlimited plan that is free to download but the service is limited to 256 kbps and is ad‑driven. MicroEsim, abesteSIM, Roamify, Yoho Mobile, Truely, Yesim, FairPlay and MTX Connect all offer unlimited data for 1 to 30 days, with prices ranging from as low as $0.00 up to roughly $92.72 USD. Several of the plans specify a speed limit of about 5 Mbps or simply note that speeds may be throttled during periods of high demand. The overall price range for unlimited travel eSIMs in Serbia therefore falls from free to just under $93, depending on provider, validity period and network technology used.

What are the major mobile networks available for a travel eSIM in Serbia?

Telekom Srbija: "The largest telecommunications operator in Serbia, offering extensive mobile coverage and services."
Telenor Serbia: "A major mobile network provider known for its wide-reaching network and customer-focused services."
A1 Serbia: "A prominent telecommunications company providing comprehensive mobile services across the country."

In Serbia, Mobile Virtual Network Operators (MVNOs) offer mobile services by leasing access from major carriers. One example is Globaltel, a local MVNO. However, most travel eSIMs rely on the infrastructure of the primary Mobile Network Operators (MNOs) rather than MVNOs.

Can I get a travel eSIM with a phone number and SMS for Serbia?

Travel eSIM plans that provide a phone number and SMS capability for visits to Serbia are available from GlobaleSIM and Roamify. All of these plans offer inbound and outbound voice calls, and SMS reception. Roamify’s plans additionally allow outbound SMS. The phone numbers are issued from foreign dialing codes—mostly +1, and some plans from +33—so they are not local Serbia numbers (Serbia’s code is +381).

Prices for these plans vary widely. Data allowances range from 1 GB up to 20 GB, and validity periods span from 7 days to 365 days, with prices starting around $4.50 USD and rising to approximately $105.00 USD for the longest, highest‑capacity packages.
