Slashtel Montenegro eSIMs start at $2.69 for 1GB over 7 days, across 6 plans. The lowest price per GB is $1.37 on the 20GB plan. A one-week trip costs from $2.69 (1GB). It connects to m:tel CG, T-Mobile and Telenor on up to 5G. Prices checked 9 October 2026.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Montenegro is $8.29 on m:tel CG, T-Mobile and Telenor. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.

No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
