First, the housekeeping. AlisaProxy now trades as ProxyBG, so if a bookmark or an older article points at the first name, this is where it lands.

What it sells is narrow and specific: mobile proxies in Bulgaria, on the A1, Telenor and Vivacom networks.

Naming the Carriers Is the Point

Every IP address carries a paper trail. Anyone checking can look up which organisation it is registered to, in a millisecond.

If it resolves to a hosting company, the site knows exactly what it is looking at. If it resolves to A1 or Vivacom, the site is looking at something indistinguishable from a phone in somebody's pocket in Sofia.

Blocking that range means blocking real paying mobile customers, which operators' subscribers would notice and sites are extremely reluctant to do.

Naming three carriers rather than saying real mobile IPs is a provider showing you the evidence rather than asking you to trust the claim.

Why Three Carriers Rather Than One

Carrier diversity is the problem people hit second, after they have solved the address problem.

If every mobile address you use belongs to the same network, they share an ASN, and any platform looking past the surface sees one operator behaving like many users.

Spreading across three operators makes a set of addresses look like a set of unrelated phones. For anyone running multiple accounts, that distinction decides whether they survive.

A Deliberately Narrow Map

Bulgaria is the whole geography, and that focus is a feature rather than a limitation.

A provider naming one country is telling you where it genuinely has SIM cards, hardware and carrier relationships. A provider naming forty is usually listing a dropdown, and you find out which mid project.

Bulgaria is also an EU member state, which matters if you need an address inside the European Union for content licensing, pricing or regulatory reasons. It is frequently cheaper to source there than in the larger Western European markets.

Unlimited Traffic and Instant Activation

Mobile data is expensive to supply, which is why most mobile providers meter hard.

Unlimited traffic here means pricing per address and absorbing the variance, so you never watch a counter during a job. Uptime is quoted at 99.9%, with activation immediate after purchase.

Who It Fits

AlisaProxy suits anyone who specifically needs Bulgarian or EU mobile addresses, multi account work needing carrier diversity, bandwidth heavy jobs on mobile connections, and users who want to know which network their address belongs to.

Who Might Look Elsewhere

If you need addresses outside Bulgaria, this is the wrong provider and no feature compensates for that.

If your targets accept residential or datacenter addresses, mobile pricing is protection you are paying for and not using. Our residential vs datacenter guide covers where that line sits.

Final Verdict

AlisaProxy is a focused geographic specialist that tells you exactly what you are buying.

Three named Bulgarian carriers, genuine EU presence, unlimited traffic, instant activation and a stated uptime figure.

If your work needs an EU mobile address, test all three operators and see which your target treats best. Verify each one presents as a carrier IP with our proxy checker.
