5SIM alternative: a private number you keep, with calls and SMS
5SIM is an online SMS verification service offering single-use numbers to receive SMS in more than 180 countries; its site says it does not support outgoing SMS and calls. If you want a number you keep for months and can also send SMS and make calls from, SMS Hallo rents real mobile numbers in 181 countries.
What 5SIM is
5SIM's website describes single-use numbers to receive SMS, available in more than 180 countries, for a long list of services including Amazon, Facebook, Telegram, WhatsApp and Google.
The site says that if no SMS is received, money is refunded automatically, and that it has a built-in AI chat assistant. Its FAQ includes sections on buying numbers via API.
The site also states that the service does not support sending outgoing SMS and calls.
How SMS Hallo differs
SMS Hallo rents real mobile phone numbers (non-VoIP, in each country's local mobile format) in 181 countries. Every number includes unlimited incoming SMS, unlimited incoming calls, 500 outgoing SMS and 1,000 outgoing calling minutes per month; allowances reset every 30 days.
The main difference is the model: SMS Hallo is a rental, not a single-use activation. The number stays yours while you renew, so you can receive a new code when an app asks again, and you can send SMS or make calls from the browser dashboard.
Sign-up needs only an email and password: no SIM card, no ID documents and no local address. Prices start from $1.80 per month on the 12-month plan ($21.60 billed yearly), the same in every country, with no setup fees. You pay in USDT or USDC on Tron, BNB Chain, Polygon, Base or Solana.
Numbers are private: while you rent a number, only you see its messages, and inboxes are never published. You keep a number by renewing for 1, 3, 6 or 12 months at a time or by turning on auto-renew. After expiry a number may be given to someone else, so renew numbers linked to important accounts.
Guarantees
Every rental comes with three guarantees: a 7-day free replacement (swap for another number in the same country, up to 3 times), a 100% refund if the number does not work with the app you rented it for (request within 7 days), and a 7-day money-back guarantee if no call or SMS has been made or received on the number.
Who each is best for
5SIM fits users who need to receive one code quickly and do not expect to use the number again, and developers who want to buy numbers via an API.
SMS Hallo fits people who want one number for an account they will keep, such as WhatsApp, Telegram or a business profile, and who may need to receive codes, texts or calls on it for months.
How to get started with SMS Hallo
1. Create an SMS Hallo account with your email and a password.
2. Choose the country you need, pick a number and choose a 1-, 3-, 6- or 12-month plan. Prices for shorter plans are shown when you choose a number.
3. Pay in USDT or USDC, either from a prepaid wallet (minimum top-up $5) or directly for the number. The payment window shows the exact amount, the address or QR code and a 10-minute countdown; send the exact amount on the same network.
4. Enter the number in the app you want to verify and read the code in your SMS Hallo inbox, where codes are detected and can be copied with one tap.
5. For accounts you plan to keep, turn on auto-renew so the number stays yours.
