How to get an eSIM with a US phone number, yourself or through an API or MCP
Yes. Our US phone plans put a real US +1 mobile number from the carrier (not a virtual number) on an eSIM, with calls, texts and data, from for the smallest plan. There is no sign-up: pay, and the eSIM is delivered as a QR code within 10 minutes of payment. An AI agent can order the same plan with search_phone_plans and create_esim_order.
What you get
- A real mobile number from the carrier, not a VoIP or app number. It receives calls and texts on the number while the plan is active, within the plan's minutes and texts.
- Mobile data on the same eSIM, for the days shown on the plan.
- The number is assigned when the eSIM is installed and first connects, and it shows on your phone.
- US phone plans work inside the United States and must be switched on there. If you need one US number while you move between countries, the worldwide phone plan gives a US +1 number that works in 160+ countries.
- Some plans can be topped up to keep the same number; others end with the plan.

How to buy one (a person)
- Check that your phone supports eSIM: look for eSIM or digital SIM in its settings.
- Open the eSIM page, choose phone number plans, then a US plan.
- Pay at checkout. Outside Nigeria you pay in US dollars by card or crypto; in Nigeria you pay naira by card or bank transfer. There is no account.
- Within 10 minutes of payment you get the QR code on the order page and by email. Install it within 60 days of buying, and switch it on once you are in the US.
How an AI agent buys one
Connect the MCP server at https://www.xpressflowsystems.com.ng/api/mcp (Streamable HTTP, no key). Call search_phone_plans with country US to get plans and prices, then create_esim_order with the chosen phone_plan_code and accept_terms set only when the person agreed to the Terms. It returns a payment_url for the person; after a verified payment the eSIM is issued within 10 minutes. Poll get_order_status with the reference and status_token.
Phone plans over HTTP (keep the ones with area US):
curl -s 'https://www.xpressflowsystems.com.ng/api/esim/plans?type=phone'Limits to know before you buy
- It is not a one-time SMS verification number. Codes often arrive, but many banks, payment apps and government services do not send codes to numbers used abroad, so we cannot promise them.
- Phone-number eSIMs cannot be cancelled or refunded once bought, even if never installed. If we cannot deliver one you paid for, we replace it or refund you.
- Keep the eSIM on your phone: a deleted eSIM cannot be reissued.
