Keep your personal number private
Your real phone number never touches Nhathuocankhang. Use a virtual number for full privacy.
So you need a second Nhathuocankhang account โ and the app immediately tells you that your phone number is already taken. Frustrating, right? Maybe you're a developer testing the registration flow, maybe you're managing prescriptions for different family members, or perhaps you run a small business and need separate ordering profiles. Whatever the case, buying a stack of physical SIM cards isn't exactly practical.
Here's the good news: temporary virtual numbers handle this cleanly. You get a fresh, working line for each account, the SMS code lands in your inbox within seconds, and your personal number never enters the equation.
Nhathuocankhang SMS verification confirms you control a phone number by sending a 6-digit OTP to that number during signup or login. With SMSPin you receive that code on a temporary virtual number online โ no physical SIM card needed and your production workflows stay separate.
No paperwork, no carrier hassle โ a real number ready to receive your Nhathuocankhang OTP code right now.

Click to get a number, then copy it to your clipboard.
Open the Nhathuocankhang app (Android or iOS) or the mobile website, start the registration, and paste the temporary number into the phone field.
Tap "Send Code" or "Verify," then switch back to your SMSPin dashboard โ the OTP usually shows up within 15โ60 seconds.
Enter the code in Nhathuocankhang. Done โ account created.
SMSPin is provided for legitimate privacy and convenience use cases only. Please review Nhathuocankhang's terms before use.
Need a specific country code for your Nhathuocankhang verification? We've got you covered.
Every SMSPin number is a legitimate, carrier-registered mobile number โ not a VoIP range. Nhathuocankhang accepts them reliably.
Sign up with email only. Your real number and identity stay private.
The moment Nhathuocankhang sends your OTP, it appears in your dashboard โ pushed, not polled.
Try requesting a resend first โ sometimes the first attempt just gets stuck.
Double-check that you selected a number from a country where Nhathuocankhang actually operates: Vietnam, USA, UK, and India are safe bets.
Still nothing? SMSPin auto-refunds your credit when a delivery fails, so you can try a different number risk-free.
For persistent failures, switch between the mobile app and the mobile website. Sometimes one channel works when the other doesn't.
| Type | Best For | Cost |
|---|---|---|
| One-time | Single verification; number expires after code arrives | From $0.01 |
| Rental | Ongoing access for days or weeks; same number stays active | From $0.02/day |
| Free trial | Testing if SMSPin works for your setup; no card needed | $0 |
Nhathuocankhang operates in Vietnam, USA, UK, India, and more โ pick a number from a country matching your registration region.
Use a fresh number that hasn't been used on the app before โ SMSPin rotates numbers regularly to avoid duplicates.
Yes, in most cases. Provided you're not violating the platform's terms of service no fraud, no harassment, no bulk spam registration a temporary number for personal or testing purposes is perfectly fine.
The usual suspects: the number's country doesn't match the app's region, the platform has already flagged the specific number, or the SMS gateway is delayed. Try a fresh number from a supported country, or request a resend within the app.
A one-time number handles a single verification and expires once the code arrives. A rental keeps the same line active for a set window, anywhere from one day to a full month, so you can keep receiving OTPs and notifications on that profile.
No. Once a number has verified one account, the app generally treats it as taken. You'll need a fresh number for each additional profile you create.
Avoid using it for banking, government services, emergency contacts, or anything that requires guaranteed long-term access. Temporary numbers expire, and if you lose access to one tied to something important, recovering it can be painful.
Yes. The service works on any platform that can display a web-based SMS inbox or call an API endpoint. Both the Nhathuocankhang mobile app and the mobile website are supported.
Yes, SMSPin issues an automatic refund when no code arrives within the standard delivery window. You only pay when a number actually works.
So you need a second Nhathuocankhang account, and the app immediately tells you your phone number is already taken. Frustrating, right? Maybe you're a developer testing the registration flow, maybe you're managing prescriptions for different family members, or perhaps you run a small business and need separate ordering profiles. Either way, buying a stack of physical SIM cards isn't exactly practical.
Here's the good news: temporary virtual numbers handle this cleanly. You get a fresh, working line for each account, the SMS code lands in your inbox within seconds, and your personal number never enters the equation. Let's walk through exactly how it works.
Nhathuocankhang ties every account to a unique phone number. Try reusing one, and you'll hit a duplicate error immediately.
A temporary virtual number gives you a brand-new line for each registration; the verification code shows up in your SMSPin inbox just like a regular text.
One-time numbers start around $0.01. Rentals keep the same number alive for days or weeks if you need ongoing access.
No code? Switch to a number from a different supported region, or try the mobile website instead of the app. If nothing arrives, SMSPin automatically refunds you.

Short version: it's their way of confirming you're a real person, and it powers everything from password recovery to order updates.
Think about what a pharmacy platform handles: prescriptions, personal health details, order histories. Nhathuocankhang needs to know that each account belongs to a verifiable human being. So during signup, they send a one-time code to whatever mobile number you provide. Enter that code correctly, and the account activates. Skip it, and you're locked out of order tracking, loyalty perks, and prescription management.
The system also enforces a one-account-per-number rule. Try registering a second profile with the same digits, and the platform usually flags it instantly or refuses to send another code. That's the wall most people hit, and it's exactly why a fresh number for each account makes sense.
If you're curious about how this verification pattern works across different platforms, take a look at our SMS verification overview.
Your personal SIM card is one number. That's it. And Nhathuocankhang, like nearly every app these days, won't let that single number power more than one account.
Try it, and you'll usually see one of two outcomes: a blunt "account already exists" message, or radio silence where the code simply never arrives because the system already recognizes your number. Even if you delete an account and attempt to re-register with the same number, many platforms enforce a cooldown period before that number becomes usable again.
Borrowing a family member's number might work in a pinch, but now you're mixing their messages with yours, and any future password reset or security alert goes to their phone. It's a privacy headache waiting to happen.
For anyone who needs more than one profile testers, families, small business owners a temporary alternative number is really the only clean workaround. Apple's App Store guidelines even push developers to implement proper unique-account verification flows, which is why this phone-number wall is so common across health and pharmacy apps.
Think of a temporary virtual number as a disposable SIM that lives entirely online. Each one is unique and hasn't been used on Nhathuocankhang before, so the app treats it like any other first-time signup. The OTP arrives in real time, you enter it, and the account goes live with no connection to your personal line whatsoever.
You've got two main options here. Grab a number for a single verification and pay only when the code actually arrives. Or rent a number for a day, a week, or longer if you expect to need it again,ย say, for password resets or repeat orders on that same profile. Numbers come from real mobile networks in supported countries, which helps them clear the app's carrier checks without issues.
This approach works whether you're using the Nhathuocankhang mobile app on Android or iOS, or the mobile website in a browser.
One note from the security community: OWASP suggests pairing SMS-based verification with sensible account hygiene. Using temporary numbers for legitimate testing or personal use is standard practice; don't use them for anything sketchy.
The whole process takes about a minute. You'll grab a temporary number from SMSPin, paste it into the Nhathuocankhang signup screen, and wait for the code to pop up in your SMSPin inbox: no second phone, no SIM swapping, no hassle.
Here's the full walkthrough:
Head to the SMSPin receive SMS page.
Look for Nhathuocankhang in the supported apps list or pick a country where the platform operates (Vietnam, USA, UK, India, and more).
Click to get a number, then copy it to your clipboard.
Open the Nhathuocankhang app (Android or iOS) or the mobile website.
Start the registration and paste the temporary number into the phone field.
Tap "Send Code" or "Verify."
Switch back to your SMSPin dashboard. The OTP usually shows up within 15โ60 seconds.
Enter the code in Nhathuocankhang. Done: account created.
You don't even need to create an SMSPin account to test a number. You can preview what's available on the pricing page before spending anything. Payment is per-use, starting at $0.01, and if the code never arrives, you get an automatic refund.
It depends entirely on what you're planning to do with the account afterward.
Registering one extra profile and never touching it again? A one-time number is your cheapest, fastest option; it starts at $0.01 and expires once the code lands. But if you expect to keep using that account over several days or weeks, receiving password reset codes, order confirmations, or any other SMS,ย you'll want a rental. Rentals keep the same number active for whatever period you choose, usually for well under a dollar.
Quick comparison:
One-time: Pay only when a code is delivered; the number expires immediately after use.
Rental: You hold the same number for a fixed period; the app won't treat each login as a brand-new verification.
Rental is ideal for QA testers, developers, or anyone running a controlled second profile that needs to stay accessible.
SMSPin offers both models with straightforward pricing and zero hidden subscriptions. Review the full number rental pricing breakdown before you commit.
Most codes show up within a minute or so. But sometimes they don't, and when that happens, it's usually one of three culprits: the app's SMS gateway is running slow, the number's country doesn't match the app's region, or the platform has flagged the IP you're connecting from.
Troubleshooting checklist:
Try requesting a resend first. Sometimes the first attempt gets stuck.
Double-check that you selected a number from a country where Nhathuocankhang actually operates. Vietnam, the USA, the UK, and India are safe bets.
Use a fresh number that hasn't been used on the app before. SMSPin rotates numbers regularly for exactly this reason.
Still nothing? SMSPin auto-refunds your credit when a delivery fails so that you can try a different number risk-free.
For persistent failures, switch between the mobile app and the mobile website. Sometimes one channel works when the other doesn't.
Code didn't arrive? We'll refund it. Switch to a fresh, region-matched number. If the code still doesn't come, you don't pay. Paid verifications start at $0.01.
Try a Paid Number
Generally speaking, yes. Using a temporary number for verification is legal in most places, as long as you're not breaking Nhathuocankhang's terms of service. Most health and pharmacy platforms allow multiple accounts for legitimate reasons family members, business use, or development testing but they draw the line at fraud, spam, and bulk abusive registrations.
SMSPin is built for privacy and convenience, not for dodging rules.
Important to remember:
"SMSPin is not affiliated with any app or website. Please follow each app's terms and local regulations."
A temporary number for one extra account is usually fine. Mass automated signups? That's likely to get flagged.
Never use virtual numbers for anything illegal, for harassment, or to misrepresent who you are.
If you're a developer testing an app's SMS flow, temporary numbers are standard industry practice.
Vietnam's Decree 13/2023 on data privacy underscores why protecting personal identifiers like phone numbers matters. Using a disposable line for non-critical registrations is simply a sensible privacy choice. Similarly, verification patterns apply to WhatsApp and Telegram.
If you're manually registering accounts one by one, stop. SMSPin has a REST API that handles the entire flow programmatically: request a number, poll for the incoming code, and retrieve the OTP without touching a browser.
It slots directly into your existing test suite or automation scripts: no separate verification tool, no SDK lock-in, just plain HTTP requests.
What the API supports:
Synchronous polling for simple integrations, or webhooks for event-driven code retrieval.
Specify a country, set a rental duration, or request the cheapest available number.
Built for QA teams who need to test account creation, password recovery, and SMS onboarding at scale.
Full documentation lives on SMSPin's site.
Google's Play Store developer docs encourage automated testing of registration flows as part of pre-release QA. A dedicated SMS verification API is the cleanest way to do that without burning through personal numbers or buying prepaid SIMs in bulk.
