Montenegro’s eSIM market is tiny. Only Airalo offers reliable plans (Yes.im and Holafly don’t cover it). You get MTEL’s network (Montenegro’s largest carrier) with decent coverage in cities and coastal areas, but spotty in mountains or rural zones. Avoid eSIM for hiking trips.
Download Airalo app → buy plan → scan QR code → activate. Works on iPhone (iOS 13.5+) and Android (10+). For dual-SIM: Put eSIM in slot 1, physical SIM in slot 2. No extra steps needed. If it fails, restart your phone—common on older models.
Montenegro’s physical SIMs are cheap ($1–2 at airports), but topping up is a nightmare. Most stores won’t sell top-up cards without ID (tourists don’t have it), apps are in Cyrillic, and staff don’t speak English. Here’s how to survive.
Airport: MTEL counter at Tivat Airport (not Podgorica)—ask for "prepaid SIM." Told to wait in line for 20 mins, but it’s worth it. At Podgorica, just buy at the MTEL booth. Convenience stores: 7-Eleven (everywhere), Spar, Mercator. No need to ask—just pick a MTEL pack off the shelf. Do not buy Vodafone—coverage is awful.
Buy at post offices (every town has one, look for "Pošta Crne Gore" sign). Staff speak some English. Pay €1–€5 for a card. Scratch it → dial *123# (MTEL) or *140# (T-Mobile) → enter code. Do not buy at 7-Eleven—stores don’t sell these.
Ask for "kreditna kartica" (top-up card). Staff hand you a card, but do not say "data"—say "kredit" (credit) or "paket" (package). Pay in cash (no cards accepted). Never works for T-Mobile at stores—only MTEL sells them.
Crucial: Dial these codes before your SIM runs out. If you wait, you’ll get a "no service" error. T-Mobile’s codes are different—stick to MTEL.
Don’t bother. You’ll waste 30 minutes trying to figure out "paket" vs "kredit." Only use apps if you’re in a big city with a local friend.
If you run out of data and can’t find a post office or 7-Eleven: Go to a hotel reception. Most hotels have MTEL SIMs for guests. Ask, "Mogu li kupiti kredit za MTEL?" (Can I buy MTEL credit?). They’ll get a voucher for €2–€5. If no hotel, ask a local for "pošta" (post office). Point to it on your map. 90% of towns have one.
eSIM is the only sane choice for Montenegro. Physical SIMs are a gamble. You’ll waste hours at stores, get rejected for top-ups, and still end up stranded without data. MTEL’s coverage is good in cities, but if you’re hiking in the Bay of Kotor or hiking in Durmitor? Good luck. The eSIM (Airalo) costs less than a coffee, works instantly, and avoids all the headache. I’ve seen tourists buy a SIM at the airport, run out of data in 30 minutes, and spend 2 hours begging for a top-up at a store. Don’t be that tourist.
