On 4 October 2026, a traveller reported that Telegram and WhatsApp did not work on T-Mobile roaming, even with a VPN, but both worked over Turkish Wi-Fi.

For MTS roaming in Turkey, travelers report an add-on priced at 500 RUB per day that includes unlimited data, SMS, and calls.

A Russian phone number may not receive the verification code for Passo Taraftar registration. As a workaround, travelers have successfully used a Turkish or Portuguese SIM number.

Besides M8, physical Travelmobile tourist SIM cards are available in Russia, providing an option for phones without eSIM support.

Travelers report that T2 currently has a promotion with 20 days of free roaming and 1GB per day. Once the daily gigabyte is used, speeds drop sharply, so heavy users may need a backup SIM or tethering from another line.

For an eSIM in Turkey, one recommendation is redesim: 20GB for 1140 RUB, with top-ups available if you run out. If your phone doesn't support eSIM, there's a physical SIM called M8 Tel.

Russian carrier Tele2 offers free roaming once a year for 15 days, limited to 1GB of data per day — an alternative to buying a Turkish SIM.

Clarification on MTS roaming in Istanbul: incoming SMS are free, but calls and sending SMS are charged (per settings confirmed at an MTS store in Russia).

For connectivity in Istanbul, check out Türk Telekom's special 'Welcome' plan with 25GB — there's a dedicated page for this offer on the carrier's website.

If traveling to Istanbul by ferry from Sochi, mobile signal is almost completely lost for about a day while at sea and returns as you get closer to shore.

A Turkish eSIM bought in advance can be paid for and activated at any time — just turn it on in your phone settings right after landing in Istanbul.

A Turkish e-SIM can be used to register on the Passo ticketing platform. SMS messages are delivered as long as the plan includes them, even if you're physically outside Turkey.

If you need a SIM that also works in Russia, check with the carrier beforehand — not all Turkish SIM cards include international roaming.

Free public Wi-Fi in Istanbul almost always requires SMS verification. If your SIM doesn't receive SMS, buy a different local SIM card that supports incoming messages.

MTS (Russian carrier) offers roaming in Istanbul — both data and calls work. A convenient option if you'd rather not buy a local SIM.

Istanbul has no internet restrictions: WhatsApp, Telegram, Instagram and other apps work freely without a VPN. A VPN is only needed if you want to access Russia-blocked content via a Russian IP.

To call Russia from Istanbul, all major messengers work: Telegram, WhatsApp, VKontakte. If the person in Russia doesn't have a VPN, VKontakte or Max calls are the most reliable options.

The easiest way to get internet upon arriving in Turkey is to buy a local SIM card from one of the main carriers: Turkcell, Vodafone, or Türk Telekom — available at the airport and throughout the city.
