SecondSIM: The Real UK eSIM for Business & WhatsApp Verification.

Yes. This is a 100% real, carrier-grade UK mobile number. It is not a VoIP (Voice over IP) or "virtual number" which are often blocked by services. It works exactly like a number from a major carrier, which is why it's trusted by banks, WhatsApp, and Google.

Yes. This eSIM will allow you to receive free inbound SMS abroad. Please note it is not designed for permanent roaming and works for scenarios when abroad to receive OTP.

Absolutely. You can purchase multiple eSIMs under a single primary account. This allows you to centrally manage billing and deployments. Once purchased, you can instantly email the activation QR code to your employee with one click from your dashboard.

By using SecondSIM eSIMs, your employees can use their existing smartphones for work. This eliminates the need for expensive second handsets, reduces hardware logistics, and moves your mobile costs to a simple, predictable monthly or yearly subscription per seat.

Instantly. Your eSIM QR code is sent to your email immediately after payment. You can activate it within minutes.

No. We do not require personal ID or business documents. We prioritize your privacy.

Yes. Our numbers are genuine UK mobile numbers (non-VoIP), so they work with WhatsApp, Telegram, Monzo, Revolut, and PayPal.

Method 1: 1-Click Install (Easiest)

If you purchased the plan on your iPhone, look for a "1-Click Install" or "Add Cellular Plan" button on the confirmation page or in your email.

Tapping this link will automatically open your iPhone's settings and jump you directly to the activation prompts. Follow the steps on-screen.

Method 2: Standard QR Code Setup

If you don't have a 1-click link, use the standard method:

1. Open Settings > Mobile Data (or Cellular) > Add eSIM.
2. Scan your QR code.

Easiest way: Open your email on a computer or another device and scan the code with your iPhone's camera.

No second device? Tap Enter Details Manually at the bottom of the screen. Copy and paste the "SM-DP+ Address" and "Activation Code" from your email.

Final Step: On-Screen Prompts

Once the plan is added, your iPhone will ask you to:

• Label Your Lines: Name your new line (e.g., "Business," "Travel," or "SecondSIM") to distinguish it from your "Personal" line.
• Set Your Defaults: Choose which line to use for Calls, Messages, and Mobile Data. You can set your new eSIM just for data and keep your personal line for calls.

That's it! You can manage your lines anytime in Settings > Mobile Data.

4. Choose Scan QR code and scan the code from your email.
5. Follow the prompts to add the new mobile plan.

Yes! This plan includes Unlimited UK Calls and SMS, so you can make and receive calls from clients on your new business number.

Simple. If your SecondSIM number fails to be verified by WhatsApp Business, your bank, Google, Shopify, or Etsy within the first 7 days of purchase, we will give you a 100% refund. We are that confident in our service. See our Terms of Service for full details.

You can cancel at any time. Your number will remain active until the end of your billing period (monthly or yearly). After that, you must sign up for our Number Parking service (£2.99/mo) to keep your number safe. If you do not park your number, it will be deactivated and recycled by the carrier. Please ensure you change your number on any accounts or port your number to your new provider by texting PAC or STAC to 65075 and follow their instructions.

Yes you can, text PAC to 65075 on your existing number. Then please submit this here.

Yes. This is a standard feature on all modern smartphones (like iPhones, Google Pixels, and Samsung Galaxies) called Dual SIM.

It is designed to let you use two separate numbers—like one for personal and one for business—on the same phone.

How does it work for calls and texts?

The technology is called Dual SIM, Dual Standby (DSDS). This means:

• Both lines are active at the same time. Both your physical SIM and your eSIM are in "standby" and ready to receive calls and texts.
• You can receive calls on both numbers. If someone calls your personal line, it rings. If someone calls your business (eSIM) line, it also rings.
• You can make calls from either number. When you make a call or send a text, your phone will ask which line you want to use. You can also set a default line for specific contacts.

The claim that you can "only use one network at a time" is misleading. While you can't be on two active phone calls at the exact same second, both numbers are always active and reachable, allowing them to work perfectly in tandem.

Unlike a virtual number app (which needs a data connection to work), an eSIM is a true, independent mobile line, giving you a more reliable connection for your second number.
