Which carriers matter, what buying a SIM involves, and when an eSIM is the smarter move.
Reliable mobile internet at better prices than most travel eSIMs, with polished iOS and Android apps and support for making and receiving phone calls.
One of the biggest travel eSIM brands, with a very large destination catalog.
Known for unlimited-data plans in many destinations, at a higher price per gigabyte.
Coverage, not price, is the whole problem: on the Pamir Highway and in the Wakhan different operators work in different valleys and long stretches have no signal at all, so carrying two SIMs (typically Tcell plus MegaFon) is normal practice on that route. When buying, expect possible fingerprinting and a request for your address of stay. Bring cash in somoni.
Generally the best coverage nationally and the usual recommendation, including the strongest current coverage in the Pamirs.
Russian-owned, with 4G in Dushanbe, Khujand and Bokhtar. Works in some Pamir valleys where Tcell does not.
Sells data packs called Mobipackets, historically valid for 90 days.
The fourth operator, a fallback rather than a first pick.
Registration against your passport is mandatory nationwide, and some operators or outlets go further, asking for a fingerprint or proof of where you are staying, so have your hotel booking to hand. You are limited to two SIM cards per person. Tourist police at Dushanbe airport and the land borders have historically issued a free 10-day Tcell SIM against a passport and e-visa; worth asking about, but do not build your plans around it.
Guac eSIM covers Tajikistan with data plans starting from $1.50 per GB and instant activation, so your phone is online the moment you land. Airalo and Holafly are popular alternatives.
