Transfer Your Mobile Number – Keep Your Number When Switching Operators

Transferring your mobile number to a new operator – known as number portability – is one of the most common questions we receive. The good news: it is simple, free, and a legal right in Sweden. This guide explains exactly how the process works, what you need to do, what can go wrong, and how to avoid common mistakes.

---

What Is Number Portability?

Number portability means that you have the legal right to keep your phone number when switching mobile operators. It does not matter how long you have had the number or which operator you currently use – the right always applies.

The regulations are established by the Swedish Post and Telecom Authority (PTS) and apply to all mobile operators in Sweden, including Tele2, Telenor, Tre, Hallon, Vimla, Fello, Comviq, Tellus, Lyca Mobile, and Chilli Mobil.

This means there is never a reason to stay with a poor operator simply because you want to keep your number. Your number follows you.

How Does Number Transfer Work?

The process is much easier than many people think and is mostly handled automatically when you sign up with a new operator.

Step 1: Choose a New Mobile Plan

Select your new operator and subscription. During signup, you simply indicate that you want to transfer your existing phone number. You usually need to provide:

• Your current mobile number
• Your current operator
• Your personal identity number for verification

Step 2: The New Operator Requests the Transfer

Your new operator sends a portability request to your current provider. In most cases, you do not need to do anything further – the operators handle the communication between themselves.

Step 3: A Transfer Date Is Scheduled

A transfer date is determined. You are normally notified by SMS or email about when the transfer will occur. Most transfers are completed within 3–10 business days after the request is approved.

Step 4: Your Number Is Transferred

At the scheduled time, your number is moved to the new operator. The interruption is usually extremely short – often only a few minutes. Afterward, your number works exactly as before, but now through your new operator.

Step 5: Activate Your New SIM or eSIM

If you received a physical SIM card, simply insert it into your phone once the transfer begins. If you ordered an eSIM, activation is completed digitally. Done.

How Long Does Number Transfer Take?

The full process usually takes between 3–10 business days from signup until the transfer is complete. If you choose an eSIM subscription, the process may be faster since no physical SIM card needs to be delivered.

During the waiting period, your old subscription and phone number remain fully active.

---

Does It Cost Anything to Transfer Your Number?

No. Number portability is completely free, and operators are not allowed to charge for the transfer itself. The only potential cost occurs if you still have an active contract with binding terms and decide to cancel it early.

eSIM – Faster Transfers Without Physical SIM Cards

eSIM, embedded SIM, is a digital SIM card built directly into your phone and activated using a QR code or app. This makes number transfers faster and more convenient since you do not need to wait for a physical SIM card in the mail.

Among the operators we compare, Lyca Mobile, Hallon, and Chilli Mobil all support eSIM. Most modern smartphones support eSIM, but it is always smart to verify compatibility before ordering.

Common Mistakes and How to Avoid Them

Mistake 1: Paying for Two Subscriptions

It is important to make sure your old subscription is actually cancelled during the transfer process. In most cases, your new operator handles this automatically, but if you have a binding contract or cancel manually, always request written confirmation.

Mistake 2: Entering Incorrect Information

If you enter the wrong phone number or operator during signup, the transfer may fail or be delayed. Always double-check all information before confirming your order.

Mistake 3: Forgetting About Existing Contracts

Transferring your number does not automatically cancel a binding agreement. You may still be responsible for remaining contract payments if you have not handled the cancellation correctly.

Mistake 4: Switching Before Paying Off a Phone Installment Plan

If you purchased a smartphone through installments connected to your subscription, the remaining phone balance may need to be paid before switching operators. Always review these terms separately from the subscription itself.

Choosing the Right Operator Before Transferring

The technical transfer process is simple, but choosing the right operator still requires consideration. The most important factors include:

Coverage

Make sure your new operator provides good coverage where you live, work, and travel. In rural areas, operators using Tele2 or Telenor networks – such as Vimla, Comviq, Tellus, and Lyca – are often strong choices.

Mobile Data

Make sure your new plan covers your actual data needs. Choosing the cheapest operator and constantly exceeding your data allowance can quickly become expensive.

Pricing and Terms

Always compare:

• total cost
• promotional pricing
• contract terms
• post-campaign pricing

Student Discounts

If you are a student, special subscriptions may offer more data at lower prices.

What Happens If the Transfer Fails?

In rare cases, a transfer may fail or be delayed. Common reasons include incorrect information, active binding contracts, or phone numbers tied to corporate accounts.

If the transfer fails, contact your new operator’s customer service – they are responsible for handling the issue. You may also contact the Swedish Post and Telecom Authority (PTS) if you believe regulations are not being followed.

FAQ – Common Questions About Transferring Mobile Numbers

Can I Transfer My Number to Any Operator?

Yes. You can transfer your mobile number to any operator offering services in Sweden, including Tele2, Telenor, Tre, Hallon, Vimla, Fello, Comviq, Tellus, Lyca, and Chilli Mobil.

Can I Transfer a Landline Number to a Mobile Subscription?

Yes. Landline numbers can also be ported to mobile subscriptions in Sweden. The process may take slightly longer and involve additional administrative requirements.

What Happens to My Contacts and Apps?

Nothing. Changing operator and transferring your number does not affect your phone, apps, contacts, photos, or login information. The only thing that changes is the SIM card or eSIM activation.

Can I Transfer My Number If I Have Debts With My Current Operator?

Usually yes. Outstanding debts normally do not prevent number portability. However, the operator may still pursue payment separately.

Do I Need to Inform People That I Switched Operators?

No. If you keep your number, everything works exactly as before for everyone calling or messaging you.

Can I Keep My Old Phone When Switching Operators?

Absolutely. Switching operators does not require purchasing a new phone. You only replace the SIM card or activate an eSIM.

What Is the Difference Between Transferring a Number and Getting a New Number?

Transferring a number means your current number follows you to the new operator. Getting a new number means receiving a completely different number instead.

How Do I Know the Transfer Was Successful?

Your new operator usually confirms the completed transfer by SMS or email. You can also test the new SIM or eSIM by making a phone call or testing mobile data.

Is It Safe to Transfer Numbers Online?

Yes. Ordering subscriptions and transferring numbers online is common and secure in Sweden. Serious operators use BankID or similar strong authentication methods. Compare and order securely through Wipick.
