Question 1

Is this a real mobile number?

Accepted Answer

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.

Question 2

What network does SecondSim use?

Accepted Answer

Our service is proudly powered by Vodafone, the UK's reliable, award-winning network. You get 4G coverage across 99% of the UK population, plus rapidly expanding 5G access. Check your local signal using the Vodafone Network Coverage Checker.

Question 3

Can I use the number abroad?

Accepted Answer

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.

Question 4

Can I manage numbers for my employees?

Accepted Answer

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.

Question 5

Do my employees' phones support eSIM?

Accepted Answer

Most smartphones released since 2019 (including iPhone XR/XS or newer, Samsung Galaxy S20 or newer, and Google Pixel 3 or newer) support eSIM technology. Before deploying eSIMs to the team, we recommend checking their device compatibility using our dedicated eSIM Device Compatibility Checker.

Question 6

How do I save money on company phones?

Accepted Answer

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. For example, equipping a 5-person team costs just £24.95/mo (£299.95/yr) total on the annual plan, saving over £1,200/yr compared to physical handsets.

Question 7

How fast do I get my eSIM?

Accepted Answer

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

Question 8

Do I need to provide ID or documentation?

Accepted Answer

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

Question 13

What is your 100% money-back guarantee?

Question 14

What happens if I cancel my subscription?

Accepted Answer

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 the number safe. If you do not park the number, it will be deactivated and recycled by the carrier. Please ensure you change the number on any accounts or port the number to your new provider by texting PAC or STAC to 65075 and follow their instructions.

Yes, absolutely! Keeping your current UK mobile number is 100% free and simple. To switch, text PAC to 65075 from your old SIM to get your authorization code. Then, log in to your SecondSim dashboard and submit our number porting form. We will handle the transition, and it will complete within 24 hours (on the next working day) with virtually zero downtime.

Question 16

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

Accepted Answer

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: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.

Question 17

Are you the 'Second Sim' app?

Accepted Answer

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

Question 18

Can I choose my mobile number?

Accepted Answer

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