100% Money-Back Guarantee

Your Remote Operations are Too Important to Risk

Using cheap VoIP or "virtual numbers" is a false economy. It costs you time, money, and your reputation when they inevitably fail.

WhatsApp Bans

VoIP numbers violate WhatsApp's Terms of Service. One day you have a business, the next your account and all client chats are gone.

Failed Verifications

"This phone number cannot be used." Banks, Stripe, PayPal, Google, and Amazon Seller accounts actively block and reject VoIP numbers.

e-Store & Client Trust

A real UK number is essential for verifying Shopify, Etsy, eBay, or Vinted stores and building professional client trust.

The Expat Banking Trap: Why UK Banks Block Virtual Numbers

When moving abroad from the UK, or traveling globally as a digital nomad, maintaining access to your UK bank accounts (Monzo, Starling, HSBC, Barclays) is crucial. However, expats consistently fall into the same trap regarding Two-Factor Authentication (2FA).

Pain Point 1: The VoIP Banking Block

Fraud detection systems at major UK banks actively detect and block SMS messages sent to VoIP apps (like Skype, Google Voice, or cheap virtual number providers). If you surrender your UK physical SIM, you will be permanently locked out of your online banking when the bank demands an SMS OTP verification.

Pain Point 2: Extortionate Roaming Fees

Some expats choose to keep their old EE, Vodafone, or O2 physical SIMs active. However, merely turning the phone on abroad to receive a single bank text can trigger a £6+ daily roaming charge. SecondSim provides totally free inbound SMS globally, avoiding roaming extortion.

Pain Point 3: "SIM Deactivation" Policies

Standard Pay-As-You-Go SIMs will forcibly deactivate and recycle your beloved UK number if you don't make a chargeable outbound call every 60 to 90 days. SecondSim's subscription model guarantees that your number is held securely for as long as you maintain the plan, without requiring you to set calendar reminders to make "fake" outbound calls.

The Solution: A Real Business eSIM

SecondSim is not a "virtual number." It's a real, carrier-grade UK mobile number to separate work and life. See the difference.

Frequently Asked Questions

Can I use this to log into my UK bank accounts from overseas?

Yes. SecondSim numbers are genuine UK mobile numbers capable of receiving 2FA SMS codes from Monzo, HSBC, Barclays, and all major UK banks globally.

Will I be charged roaming fees to receive a simple SMS text?

No. Receiving SMS texts on your SecondSim while abroad is free, making it perfect for expats needing banking verification.

How do I install it if I am already out of the UK?

It is an eSIM. You purchase online, receive a QR code via email instantly, and activate it immediately on your compatible phone without waiting for international shipping.

Is this a real mobile number?

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.

Can I use the number abroad?

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.

Can I manage numbers for my employees?

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 1-click link to your employee with one click from your dashboard.

How do I save money on company phones?

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.

How fast do I get my eSIM?

Instantly. Your eSIM 1-click link is sent to your email immediately after payment. You can activate it within minutes.

Do I need to provide ID or documentation?

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

Will this work for WhatsApp and Banking Apps?

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

How do I install on an iPhone?

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 1-Click Setup

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

  1. Open Settings > Mobile Data (or Cellular) > Add eSIM.
  2. Use your 1-click install link.

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.

See our complete iPhone Setup Guide →

How do I install on Android (Samsung/Pixel)?

Very similar to iOS (menu names may vary slightly):

  1. Go to Settings > Network & internet (or Connections).
  2. Tap SIMs (or SIM card manager).
  3. Select Add eSIM (you may need to tap a '+' icon first).
  4. Choose Scan QR code and scan the code from your email.
  5. Follow the prompts to add the new mobile plan.

See our complete Android Setup Guide →

Does this include calls or data?

Yes for calls, no for data! This plan includes Unlimited UK Calls and SMS, so you can make and receive calls from clients on your new business number. Data is used seamlessly from your primary physical SIM or Wi-Fi connection.

What is your 100% money-back guarantee?

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.

What happens if I cancel my subscription?

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.

Can I bring my number?

Yes you can! Text PAC to 65075 on your existing number. Then please submit our number porting form.

Can I use an eSIM and my physical SIM at the same time?

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.

Are you the 'Second Sim' app?

No. We are a UK Telecoms Operator. We provide real numbers via eSIMs, not VoIP.

Can I choose my mobile number?

No, numbers are automatically assigned from our pool of real UK mobile numbers upon activation. This ensures immediate availability.

Managing a team? Deploy numbers instantly.

SecondSim transforms how businesses handle telecom. Instead of managing hardware logistics or processing individual £15 expense claims, you deploy digital UK mobile numbers directly to your team's existing devices via our zero-touch admin dashboard.

When a new employee joins, enter their email and click "Send to Employee." They instantly receive a 1-click installation link that activates a secure, secondary business line on their personal phone. You get one simple monthly corporate invoice for the whole team.
