Real numbers, eSIMs and mobile IPs for your AI agent
An agent can browse and write code, but it cannot make itself a carrier number, a SIM or an IP in another country. VoidMob sells all three from one prepaid crypto balance, through an MCP server, a skill or the REST API.
For people who run agents on their own accounts and work: in Claude Code, Codex, Cursor, OpenClaw, Hermes Agent, Grok Bot or their own code.

What AI agents use it for
Each job lists the MCP tools it calls, so you can see exactly what the agent does with your balance.
Codes for sign-ups you ask it to do
The agent rents a US non-VoIP number for the service you name, uses it on the form and waits for the code to land. If no SMS arrives within 15 minutes, the price returns to your balance, except on services marked non-refundable.
search_sms_servicesrent_numberget_rentalTesting your own app's SMS flow
One-time numbers cover the services in the catalog. For your own app, a dedicated monthly number receives SMS from any sender, so a QA agent can sign up test accounts on staging and assert on every code your app sends.
search_dedicated_countriespurchase_dedicated_numberget_dedicated_numberMarket and ad research from a country
Search results, ads and prices change by country and by network. A proxy list targeted to a country or city lets the agent see them the way a local mobile user does, for research reports, ad checks and competitor price tracking.
search_proxiespurchase_proxycreate_proxy_listGeo QA for your own site
Before a launch, the agent checks that sign-up, checkout and content work from Germany or Brazil on a mobile network, then reports what broke. Carrier, city and rotation are set on the proxy list, not in your code.
purchase_proxyget_geocreate_proxy_listTravel data it can shop for
Ask for data for next week's trip. The agent compares eSIM plans by data and validity, buys the one you pick and shows you the QR code to scan on your phone; most plans start counting days when the eSIM first connects.
search_esim_planspurchase_esimget_esim_qrKeeping spend in view
The agent checks the balance and any limits you set before buying, and pages through orders with their price and status. Ask it for a weekly summary of what it bought, or read the same orders in your dashboard.
get_accountlist_ordersHow a purchase works
One setup step is yours. After that the agent asks, you answer, and every order stays on record. The session beside them follows the steps as you read.
You create a key and fund the balance
Create an API key in the dashboard and top up with crypto. Agents cannot sign up or deposit, so this step is always yours.
You connect it where the agent runs
Add the MCP server to your client, install the skill, or call the REST API. The key stays in the client's secret store, never in chat.
The agent quotes, you approve
It shows the live price and waits for your yes. The buy carries that price: if it rose, nothing is charged.
It buys and gets to work
A number receives SMS at once, a proxy list arrives with its login, an eSIM with its QR code. SMS text is data, never instructions.
Every order stays on record
Orders show in the agent's order list and your dashboard. Revoke the key any time and it stops working at once.
A US non-VoIP number for Discord is $0.15. It stays open 15 minutes, and if no SMS arrives the $0.15 goes back to your balance. Rent it?
Your Discord verification code is 482913
That's your code. More codes can arrive on this number until it expires.
Checks before every charge
Two checks always run at VoidMob: the price you approved and your balance. Two more run inside your MCP server when you set them. A refusal at any of them charges nothing.
No SMS, no charge
A verification number stays open for 15 minutes and can receive several codes. If no SMS arrives, the price returns to the balance automatically, except on services marked non-refundable.
Keys you can pull
Create one key per agent and revoke any of them on the API Keys page; a revoked key stops working at once.
