Bulgaria 4G/5G mobile proxies

Which mobile networks can I use in Bulgaria?

Mobile IPs in Bulgaria come from SIM cards on A1, Vivacom, Yettel. Bulgaria has three MNOs: A1 (3.95 million subscribers in 2025), Vivacom and Yettel (3.2 million in 2025). Median mobile download was 203 Mbps in August 2026, 10th worldwide.

Well-known brands and MVNOs that run on these networks include the operators above. A mobile IP from any of them belongs to the address ranges of its host network.

Why do websites trust mobile IPs?

Mobile networks share a small pool of public IPv4 addresses between many subscribers through carrier-grade NAT (CGNAT, RFC 6598). One mobile IP can therefore carry traffic from many real phones at once.

Websites know this, so they rarely block a mobile IP outright. This is a mechanism, not a guarantee: behaviour that breaks a site's rules still gets flagged. Learn how to check an exit IP in our ASN lookup guide.

What are Bulgaria mobile proxies used for?

Bulgarian IPs show local Google results and prices on eMAG.bg, Pazaruvaj.com and Technopolis. Since 1 January 2026 local prices are in euro, which matters for price-monitoring data.

With a mobile IP in Bulgaria, teams typically:

• test apps and mobile checkouts as customers on A1, Vivacom see them;
• verify mobile ads and app-install campaigns shown in Bulgaria;
• track mobile search results on google.bg;
• manage brand and client social media accounts from a stable local IP.

How do I change the IP of a Bulgaria mobile port?

Each dedicated port has its own rotation link. Call it and the modem reconnects to the carrier, which usually assigns a new IP within seconds:

Replace {port} with your port number and API_KEY with your key from the client area. You can also set an automatic rotation timer. Connection details for HTTP and SOCKS5 are in the quickstart guide.

Is it legal to use mobile proxies in Bulgaria?

Using a proxy is legal in Bulgaria; what matters is what you do through it. Scraped personal data falls under the GDPR and the Bulgarian Personal Data Protection Act, supervised by the CPDP.

PontProxy blocks online banking, government portals, payment processors and outgoing email (SMTP ports 25, 465 and 587), and every account follows our Acceptable Use Policy. Mobile ports are not for SMS verification, account farming or ban evasion.
