  • goAFK stands out for payment from Russia (MIR cards and SBP), unlimited plans and its listing in the Claude connectors directory.

How we compared

On 2026-11-13 we opened the "for AI agents" pages of the services ChatGPT shows for "how to buy an eSIM with an AI agent" and recorded their MCP tools, how you get access, who completes payment and how many destinations they cover. We do not compare prices here: how the purchase works matters more.

Wording follows each service’s own page; we did not test them with a purchase.

The key question: who pays

There are two models. Either the agent only prepares the purchase and returns a link, or the agent holds a wallet or payment credential and pays itself.

When you want an agent that pays itself

If you are building an autonomous agent with its own crypto budget, look at eSIM Tabby, BuyUKeSIM, SimFuse, AgentRoam. You will be trusting the agent with a wallet or credential, and it will pay for its own mistakes in picking a plan.

When it is better for a person to pay

For a normal trip, "the agent picks, the person pays" is simpler: the agent never sees a card and you confirm the purchase yourself. That is how goAFK works: the agent searches plans by country, city or region, explains installation and returns a payment link on goafk.io.

What makes goAFK different

  • Connect in a minute: no API key, no account, nothing to install; one click in Claude from the connectors directory.
  • Payment from Russia through the agent’s link: MIR cards and SBP in rubles, plus crypto, international cards and Apple Pay.
  • Unlimited plans for 7, 15 and 30 days (first 3 GB a day at full speed), 148 countries and regional plans.
  • The server stores nothing from the conversation and charges nothing: every tool is read-only.

Connecting goAFK to your agent

In Claude, open goAFK Travel eSIM in the connectors directory and select Connect. In ChatGPT, Cursor, Claude Code and other MCP clients, add the server at goafk.io/mcp with no authentication. Step-by-step instructions are on the "Buy a travel eSIM with your AI agent" page.

After payment the QR code appears on the order page. The eSIM must be activated within 180 days, and plan validity starts at the first connection in your destination.
