In mountainous areas like Vayots Dzor, your phone may work harder to find a tower, consuming more battery. It is recommended to switch your network selection to "Manual" and lock it to the strongest carrier (usually Viva-MTS) provided by your eSIM profile to prevent constant network switching and battery drain. 

 While local data is cheap, roaming eSIMs often have a daily high-speed cap followed by throttled speeds (e.g., 128kbps) if you purchase an "Unlimited" plan. For heavy users staying in Yerevan, a fixed GB package (e.g., 10GB or 20GB) is often superior to "Unlimited" plans to guarantee max 4G+ speed without throttling. 

 The North-South highway has good coverage, but expect short "dead zones" in the high mountain passes near Sisian and Goris. The connection usually switches automatically between Edge and 4G. It is highly recommended to download offline maps (Google Maps or Maps.me) before driving this specific route. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

 No, Armenia has very open internet freedom. WhatsApp, Telegram, and Messenger calls are clear and unblocked. In fact, Telegram is the primary method of communication for many local businesses and tour operators, so having data to use it is more important here than standard SMS. 

 Coverage on the TCT is surprisingly decent but intermittent. In dense forest sections of Tavush and Lori, signal may drop. An eSIM connected to Viva-MTS offers the best chance of retaining signal on higher elevations along the trail for safety/GPS usage. 

 Most premium eSIMs connect to Viva-MTS (formerly Vivacell) or Team Telecom. For travelers heading to remote regions like Dilijan National Park or the southern Syunik province, an eSIM using the Viva-MTS backbone is preferred as they historically have the widest 4G/LTE geographical coverage compared to Ucom, which is excellent in Yerevan but can be spotty in deep gorges. 

 Armenia is primarily a 4G+ (LTE Advanced) country. While operators like Team Telecom and Ucom have launched 5G in central Yerevan (Kentron district) and Gyumri, do not expect consistent 5G outside the capital. Your eSIM will mostly rely on very stable and fast 4G+ networks, which are sufficient for HD streaming. 

 Yes, tethering is fully supported. This is vital for "workation" travelers in Gyumri or Dilijan, where café Wi-Fi can sometimes be unstable during power fluctuations. Your eSIM acts as a reliable backup to keep your laptop connected. 

 This specific plan is valid only within Armenia. This is the most important question for "Caucasus Tour" travelers. If you take the train from Yerevan to Tbilisi (Georgia) or cross the border to Iran, your connection will stop. For a seamless multi-country trip, we highly recommend our Regional eSIM (e.g., "Caucasus" plan) which covers both Armenia and Georgia. 

Yes, 100%. Buying a physical local SIM card (like Team or Viva) at Yerevan (EVN) Airport requires you to find the kiosk, wait in line (often after a 4 AM flight), and go through a mandatory passport registration process. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land. 

Yes, in all key areas. Armenia has an excellent 4G network. Our eSIM connects to premium local networks (like Team/Viva) to ensure you have a strong signal not just in Yerevan, but also at Lake Sevan, in the towns of Dilijan, and even at remote monasteries like Tatev and Geghard. 

Yes, absolutely. Yerevan is a global "Digital Nomad" hub. Our eSIM provides high-speed, low-latency 4G/LTE data, which is perfect for Zoom/Teams calls, remote work, and bypassing the (often slow) Wi-Fi in cafes. It is a secure and stable connection for your professional needs. 

No! This is the #1 roaming trap. Although Armenia is in Europe, it is NOT a member of the European Union (EU). Your "Roam Like at Home" (RLAH) plan does not apply. Most EU, UK, and US carriers (like AT&T, Vodafone, O2, T-Mobile) will charge you extremely high "Rest of World" international roaming rates (e.g., $10-$15 or £6 per day). A Cellesim eSIM is the only way to get a fixed, cheap data price.
