Bulgaria mobile proxies are connections whose requests reach the internet from the IP address of a Bulgarian mobile carrier. At LTESpace that carrier is A1 Bulgaria, with modems in Sofia. Bulgaria is an EU country in South-Eastern Europe with advertising that is inexpensive by European standards, so it is used both as a market in its own right and as an affordable European exit point.
Why Bulgaria is a location of its own
Bulgaria is a member of the EU and the Schengen Area, has used the euro since 2026, and its websites run in Bulgarian, written in Cyrillic. For websites it is a separate market: its own language, its own Google.bg results, its own ads and local platforms.
A Bulgarian mobile IP gives a platform a clear signal: the visitor is in an EU country and goes online from a smartphone. The address belongs to a cellular carrier, and ordinary subscribers use it at the same minute. Why platforms treat mobile addresses this way is explained in CGNAT in mobile proxies.
Where Bulgaria mobile proxies are used
- ads for a Bulgarian audience: checking impressions, ad language and landing pages;
- European ads with affordable traffic: Bulgaria is often tested first before a campaign scales to neighbouring EU countries;
- search results and SEO: rankings for Bulgarian queries and Google.bg mobile results;
- accounts on European platforms: a consistent profile where the address, language and time zone point to one country;
- website testing: Bulgarian localisation, prices in euro, delivery and payment methods.
Bulgaria mobile proxies for advertising
Ad accounts compare the country of the address with the account country, the system language and the time zone. Bulgaria runs on Eastern European Time, UTC+2 in winter and UTC+3 in summer. If the address is Bulgarian but the browser lives on another country’s time, the platform sees a mismatch. How to avoid it is shown in mobile proxies, time zones and antifraud, and how to prepare an address before a launch in IP warm-up before launching ads.
Mobile carriers in Bulgaria
The Bulgarian market has three mobile carriers: A1, Vivacom and Yettel. Each assigns addresses from its own ranges.
LTESpace channels run on A1 Bulgaria, a large network that belongs to the A1 Telekom Austria group. All connections go through one carrier in Sofia, so addresses from different networks and cities never mix within one session.
Bulgaria mobile proxy plans and prices
- Shared: up to 5 customers per channel, up to 100 simultaneous connections; $1.72 a day, $3.61 a week, $6.02 for 2 weeks, $8.6 a month, $23.22 for 3 months;
- Private: a channel for one customer with no connection limit; $8.6 a day, $18.06 a week, $30.1 for 2 weeks, $43 a month, $116.1 for 3 months.
Both plans come with unlimited traffic and connect over HTTP or SOCKS5. Bulgaria is one of the most affordable European locations at LTESpace.
Availability changes: when all Bulgarian channels are taken, the country disappears from the order form. Support can confirm availability.
How the IP changes
A shared channel changes its address on a timer, every 5 minutes. A private one changes it by link or API when you need it, or on a timer from 1 to 60 minutes. For ad accounts and other accounts a private channel with link-based change works better: the address holds for the whole session. More in mobile proxies with rotation.

When Bulgaria is not the best choice
- large Western markets such as France, Spain or Germany need an address from that country;
- if you need a choice between carriers in one country, Bulgaria currently has one;
- if the country does not matter at all, any cheaper location will do.
Summary
Bulgaria mobile proxies give you an address on the A1 network in Sofia, in an EU country with the euro, Cyrillic script and affordable advertising. A shared channel costs $8.6 a month, a private one $43, traffic is unlimited, and terms run from one day to three months. Choose a plan in LTESpace pricing.
