How to Get a Second Phone Number Without a Second SIM or Phone

Short answer: You can get a second phone number without a second SIM by using a virtual number, which receives SMS in an online account instead of on a SIM card. An eSIM Signal virtual number gives you a UK, Australian or Brazilian mobile number with free incoming SMS, outgoing SMS from your account and no contract, readable on the phone you already have. If you also need calls on the second number, a second eSIM line from a mobile network is the alternative.

Why people want a second number

A second number is less about gadgets and more about keeping parts of life apart:

• Privacy: marketplace listings, dating apps, newsletters and loyalty schemes, without handing out your personal number
• Side projects: a small online shop, tutoring, a holiday let or freelance work
• Another country: a UK, Australian or Brazilian number while you live somewhere else
• Verification: a separate number for codes, so your personal number is not in every database
• Testing: checking how an app's SMS flow works in another country

Option 1: a second SIM in a dual SIM phone

Many phones have two SIM slots, or one slot plus eSIM. Add a second SIM from a mobile network and you have two full numbers with calls, SMS and data.

• Good for: a full second line you also want to call from
• Downsides: a monthly plan or top-ups to manage, often an address or ID in that country, and it only works if your phone has a free slot

Option 2: a second eSIM line

Most modern phones can hold several eSIM profiles, with one or two active at a time. A network's eSIM gives you a second full line without a plastic card.

• Good for: a full second line on a phone that supports eSIM; check yours on our supported devices page
• Downsides: like any mobile line, it usually needs a contract or local registration, and most phones only run two lines at once, which is a problem if you also want a travel eSIM

Tip: a travel eSIM is data only and will not give you a second number. If you want data abroad and a second number, see virtual number vs eSIM.

Option 3: a virtual number for SMS

A virtual number lives in an online account, not on your phone. It uses none of your SIM slots, so it works alongside whatever lines you already have.

With eSIM Signal:

• Real mobile numbers in the UK (+44), Australia (+61) or Brazil (+55)
• Free, unlimited incoming SMS, readable in your account from your phone or computer
• Outgoing SMS sent from the account, charged per message
• Any available number free, or choose a specific one for a small one-off fee
• No SIM, no second phone, no contract
• SMS only: no calls

• Good for: privacy, codes, listings, a number in another country, a side project that only needs texts
• Downsides: no calls, and a few services (some banks and messaging apps) refuse virtual numbers

Which option should you choose?

• You need calls on the second number: a second SIM or eSIM line from a mobile network.
• You only need texts and codes: a virtual number is quicker and has no contract.
• You need a number in a country you do not live in: a virtual number, because local lines often need a local address or ID.
• Your phone has no free SIM slot, or you use it for travel eSIMs: a virtual number, because it uses no slot at all.

Setting up a second number for privacy

1. Get the number in the country you need. The UK is the most flexible, with 1, 3 or 12-month plans.

1. Use it for anything public: listings, sign-ups, newsletters, loyalty cards and one-off purchases.
2. Keep your personal number for family, friends, your bank and your employer.
3. Reply from the account when you need to, so your personal number never appears.
4. Switch renewal off when the project ends, and the number simply stops on its paid-until date.

Common mistakes

• Putting a second number on a long-term account and then cancelling it. Move important accounts back first.
• Using a public free SMS site as a "second number". Anyone can read those messages; see free SMS websites vs a private number.
• Expecting a travel eSIM to act as a second number. It gives you data, not a number to give out.
• Giving a virtual number to someone who needs to call you. Ours are SMS only.

Frequently asked questions

Can I have a second phone number on the same phone?

Yes. Either add a second SIM or eSIM line if your phone supports dual SIM, or use a virtual number, which lives in an online account and needs no SIM slot.

Do I need a second SIM for a second number?

No. A virtual number receives SMS online, so it works with the SIM you already have, or with none at all over Wi-Fi.

Can I call from a second virtual number?

Not with eSIM Signal. Our numbers are SMS only: free incoming SMS and outgoing SMS from your account.

Is a second number good for privacy?

Yes. Using a separate number for listings, sign-ups and newsletters keeps your personal number out of public view and out of marketing lists.

Can I cancel my second number at any time?

Yes. Switch renewal off and the number ends on its paid-until date, with no contract or cancellation fee.
