Our verdict
Telekom Slovenije suits people in Slovenia who want a SIM-only line with unlimited data on the operator's own network, held on a 24 month contract at €10.99. The trade-off is that this rate is promotional, so budget for the regular monthly fee once the discount period ends.

Pros and cons
Pros
- Unlimited domestic data on the SIM-only Naj B plan at €10.99 with a 24 month contract
- Operates its own mobile network rather than reselling one, with coverage of 99% of the home market
- An eSIM and wifi calling are both supported, so a recent handset needs no physical card and calls continue over a broadband connection
- Billing runs both ways through contract and prepaid, so a shorter line does not force a long commitment
- EU roaming is included in the plan, so use across the EU zone adds nothing separate
Cons
- The monthly fee on offer is promotional, and the regular fee is charged once the discount period ends
- Unlimited data on Naj B at €10.99 still sits under a fair use threshold, so heavy use faces limits
- Data rollover is not offered, so an unused allowance is lost when the period closes
- Lonestar Cell MTN lists a starting price of $0.20, a lower entry figure than the €4.99 here
Who it suits
- People living in Slovenia who want voice and a large data allowance on the same network bill
- Customers ready to commit to a 24 month contract to hold the promotional rate
- Anyone with a recent handset who wants an eSIM and wifi calling on the same line
Who should look elsewhere
- Travellers who would rather sit on a different underlying network: yesss! runs on A1, so signal abroad is worth comparing there
- Visitors after a short prepaid line, since the unlimited Naj B plan runs on a 24 month contract while GETESA bills both ways through prepaid and contract
- Buyers who expect unused data to carry into the next period, as data rollover is not offered on this network
Pricing
Entry starts at €4.99 on Naj Naprava, a small plan with a light data allowance and no contract stated. The plan most readers will actually compare is Naj B, a SIM-only plan with unlimited domestic data on a 24 month contract at €10.99. The cheapest unlimited plan is the same Naj B plan, so the starting point for unlimited data and the starting point for a generous SIM-only allowance both land on €10.99. Billing runs both ways, through contract and prepaid, so a shorter prepaid line is possible even though the unlimited plan is tied to a contract. The detail that matters at renewal is the promotional rate. It holds for the length of the contract when the order is placed in the Moj Telekom app, and for a shorter stretch through other sales channels. After the discount ends the regular monthly fee is charged, and the provider reserves the right to change regular prices and terms. So the figure at entry and the figure at renewal are two different numbers, and the second is the one worth budgeting for.
Where it sits among rivals
On price from, the brand sits at position 93 out of 258 listed plans, so the opening figure is unremarkable against the field. On unlimited price the picture changes: position 27 out of 173 places the unlimited rate far higher up a shorter list. That gap is the trade-off in a single line. Readers shopping on the first bill will find cheaper sellers above; readers shopping on what unlimited data costs each month will find very few cheaper. The same split shows up in the reference prices, because the cheapest SIM-only plan with a generous allowance and the cheapest unlimited plan are the same Naj B plan, so there is no second and cheaper route into unlimited data here. Entry price is where the field is crowded, so a reader comparing on the smallest number will not land on this brand. A reader comparing on unlimited data is more likely to.
What it does well
Coverage is the strongest point, standing at 99% of the home market. That figure describes the domestic network rather than a promise about other countries, which is the right way to read it. On features, 5G is supported, an eSIM is available, and wifi calling is offered, so calls can continue over a broadband connection when a handset cannot hold a signal. An eSIM also means a recent handset can be activated without waiting for a card to arrive. The single gap in the list is data rollover. Unused allowance does not carry into the next period, so a light month is a wasted month rather than a cushion. Readers who treat a monthly line as a fixed budget may prefer a plan that rolls the balance over.
Who runs it
The seller is the network itself, Telekom Slovenije, d.d., based in Slovenia and operating its own mobile network rather than reselling another provider's signal. It has traded since 1991, which places it among the longer established operators in its home market. A domestic operator of that age is a sensible default when the line has to work reliably at home rather than on a visiting network. Support runs on phone, email and help centre, so help is available by phone, by email and through an online help centre. Reachability is the practical trust marker here: a provider you can ring in the market it serves, running the towers the coverage figure refers to.

Frequently asked questions
What does the plan cost each month?+
Entry prices start at €4.99 on Naj Naprava, a small plan with a light data allowance and no contract stated. The unlimited SIM-only Naj B plan runs at €10.99 on a 24 month contract, and that same plan is also the cheapest unlimited option in the range.
What happens to the price when the discount ends?+
The monthly rate on offer is promotional and lasts for the length of the contract when the order is placed in the Moj Telekom app, or a shorter stretch through other sales channels. After the discount ends the regular fee is charged, so treat €10.99 as an entry figure rather than the ongoing one.
How long is the contract?+
Plans on this brand run for 24 months, which is longer than most of the plans listed across the site. Readers who want a shorter commitment have a second route through contract and prepaid, since prepaid billing is offered alongside contracts.
Is the data allowance really unlimited?+
Naj B is sold as unlimited domestic data at €10.99, but a fair use threshold applies, so heavy use can be limited. Data rollover is not offered either, so anything left unused at the end of the period is lost rather than carried into the next one.
What coverage can I expect, and does the plan work abroad?+
Coverage stands at 99% of the home market, and EU roaming is included in the plan. The coverage figure describes the domestic network, so it should not be read as a measure of reach in other countries.
Can I get an eSIM and use wifi calling?+
An eSIM and wifi calling are both supported, alongside 5G, on a network that reaches 99% of its home market. An eSIM lets a recent handset activate without waiting for a card to arrive, and wifi calling carries calls over a broadband connection where signal is weak.
Who runs the network, and how do I reach support?+
The seller is the network itself, Telekom Slovenije, d.d., based in Slovenia and operating its own mobile network. It has traded since 1991. Support runs on phone, email and help centre, so help is available by phone, by email and through an online help centre.
How does it compare with other sellers on price?+
On price from the brand sits at position 93 out of 258, which is mid-table. On unlimited price it ranks at position 27 out of 173, a much stronger showing. Entry price is the weaker of the two comparisons.
