Russia's 'No SIM City': How Foreign SIM Card Blocks Impact Tourists and Locals (2025)

Imagine being completely cut off from the digital world the moment you cross a border. That's the reality many faced in Russia recently, and it's all thanks to a controversial "cooling-off period" for foreign SIM cards. This initiative, intended to bolster security, has instead caused widespread chaos and frustration. But here's where it gets controversial... was this really about security, or something more? Let's dive into the details.

Earlier this month, Russian telecom operators began implementing a 24-hour mobile internet blackout for all foreign SIM cards. The stated goal? To curb drone activity, particularly near the country's borders. Think of it as a digital quarantine for your phone upon arrival. The idea, at least on paper, was that this "cooling-off period" would prevent nefarious actors from using foreign SIMs to control drones and potentially cause harm.

The concept of this "cooling-off period" first emerged in early August 2025, when Russia’s Digital Development Ministry floated the idea. Digital Development Minister Maksut Shadayev publicly stated the restriction was designed to "combat SIM cards used in drones." He suggested that mobile internet access via foreign SIM cards would be unavailable for at least five hours upon entering Russian territory. The specific duration of this "cooling-off period," he added, was still under consideration. So, the initial plan was a few hours, but it quickly escalated.

Now, about how this was supposed to work. According to a source who spoke with Vedomosti, regaining internet access would require foreign SIM card holders to complete a CAPTCHA on a special website. The logic was simple: drones can't pass CAPTCHAs, so the threat would be neutralized. And this is the part most people miss... Igor Bederov, head of information and analytical research at T.Hunter, pointed out a significant flaw: the restrictions wouldn’t entirely eliminate the drone threat. Why? Because drones could still use Russian SIM cards or connect via other channels, including satellite internet. It's like trying to stop a leak with a single finger in a dam.

The Digital Development Ministry remained tight-lipped about when this "cooling-off period" would actually take effect. However, on October 6th, several Belarusian telecom providers preemptively warned their subscribers about potential service disruptions while roaming in Russia. They later clarified that the block would last a full 24 hours and affect not only mobile internet but also text messaging. Double whammy!

Almost immediately, complaints flooded Telegram channels from users unable to access mobile internet with foreign SIM cards, including eSIMs. Voice calls and regular SMS seemed to function, but data was a no-go. A report from Mobile Review suggested the restriction had already been in place for a week in regions near the Ukrainian border, though without providing a source. The Insider also highlighted some unusual technical quirks. The "cooling-off period" could reportedly trigger even when crossing borders between Russian regions. Furthermore, Nasvyazi, a project monitoring internet outages, indicated that mobile internet access would be blocked again if a device remained inactive for more than three days, and the 24-hour timer reset whenever the device switched to a different network – a common occurrence while roaming. So, imagine driving across Russia and constantly losing your internet access!

But here's where the real problems began. By mid-October, it became clear the entire system was in disarray. Kommersant reported that Russian mobile operators were struggling to implement the restrictions effectively. Users were unable to access mobile internet even after their "cooling-off" period had expired, and SMS messages weren’t being delivered either. It sounds like a technical nightmare.

Out of Russia’s four major telecom providers, only T2 managed to implement the 24-hour timer, according to a telecom insider speaking to Kommersant. Even then, T2 users still experienced SMS disruptions. The source claimed that other operators lacked the technical capability to limit the block to a single day, resulting in data and SMS restrictions lasting for the entire duration the foreign SIM card remained in Russia. The source estimated that it would take at least three to four weeks to get the system running properly. But this raises a critical question: if the technical infrastructure wasn't ready, why implement it in the first place?

Adding fuel to the fire, representatives from T2, MTS, MegaFon, and Beeline all declined to comment on the issues. The Digital Development Ministry has also remained silent, not even confirming the "cooling-off period" is officially in effect. The silence is deafening, isn't it?

While the mobile internet disruptions primarily impacted foreign visitors, the SMS delivery failures also affected some Russians, particularly those using bank cards issued abroad. Many had opened foreign accounts to pay for international online services, but now they couldn’t receive text notifications, such as verification codes from their banks. This seemingly small restriction has significant implications for everyday financial transactions.

For tourists visiting Russia, the situation is even more dire. Getting online now requires a Russian SIM card, which has become virtually impossible to obtain in 2025. Foreigners must first create a verified account on the Russian government’s public services portal (Gosuslugi), submit a notarized translation of their passport, obtain a SNILS (similar to a social security number), provide biometric data, and then register it through a bank. The process can take days, and only after completing it can a mobile carrier sign a service contract. These burdensome requirements led telecom providers to reportedly ask the Digital Development Ministry to simplify the rules.

And even with a Russian SIM card, internet access isn't guaranteed. Since the summer, authorities across multiple regions have periodically shut down mobile internet in an effort to counter Ukrainian drone attacks. During these blackouts, only websites included on so-called “whitelists” remain accessible. It's a digital lockdown within a lockdown!

So, what's the real story here? Is this cooling-off period a legitimate security measure, or a veiled attempt to control information and limit access to the outside world? Is it a sign of increasing isolation, or simply a poorly executed plan? And what does this mean for the future of internet freedom in Russia? Let us know your thoughts in the comments below. Do you think this is a justified security measure, or an overreach of government control? We want to hear your opinion!
