Vodafone SIM Won’t Activate: How To Activate SIM Card

Are you having a problem with your Vodafone SIM that just won’t activate?

Don’t worry; this article will guide you through the correct procedure, whether you have a new or replacement SIM.

Why Isn’t My Vodafone SIM Activated Yet?

When you purchase your Vodafone SIM card from a retail shop, you can immediately use it on your mobile phone. All the settings come pre-activated, so you only need to wait a few hours to use your new Vodafone SIM card.

However, if the company sends you a replacement SIM card or you are a Pay Monthly customer, you need to activate it first before you can use it. Activating is easy. You can do it either through the Vodafone website or through your mobile phone.

How Do I Activate My Vodafone SIM UK?

In the UK, you can activate your SIM online if you’re a pay monthly customer. However, If you got the SIM in a Vodafone shop, it will be activated already. If you ordered the Vodafone SIM online, call 17298 after inserting it into your mobile phone.

Pay Monthly customers need to activate their SIM cards in the UK by the following methods.

Go to the Vodafone Website

  • Go to the Vodafone website
  • Click on My Vodafone from the top menu
  • If you are a new user, click on Register and fill in the required personal information to create a new account
  • Once you complete the registration, click on My Vodafone again
  • Login with your login credentials
  • Locate the My Device and SIM section on the My Vodafone page and click on it
  • Click on My SIM and then click on Activate Your New SIM
  • Check that your SIM number is correct and hit Activate

Use Your Mobile Phone

  • Mobile number of the SIM card you are trying to activate
  • Your Vodafone account’s 4-digit inquiry PIN that you created at the time of the registration
  • Type in the first 20 digits of your SIM card number

Calling Vodafone Customer Support

  • Call the Vodafone SIM replacement service number
  • Wait for the voice recording to answer on the other end of the line
  • Enter the mobile number, 4-digit PIN, and 20-digit SIM card number when the voice prompts you to do so
  • Wait for the system to begin the activation process and end the call when you are notified
  • It will take 2 to 24 hours to process your SIM activation request and activate it
  • Afterward, start making calls and send text messages to confirm the activation

How do I activate my Vodafone SIM swap?

  • Under Activate SIM, enter the phone number you want to move to your new SIM
  • You can also contact the chat option on the page to contact Vodafone support to issue you a replacement SIM
  • Once you get the replacement SIM, go to the Vodafone website
  • Log in with your username and password and head to the SIM activation form
  • Click SIM Swap, located at the right side of the page
  • Type in your Vodafone account’s 4-digit inquiry PIN that you set when you registered with Vodafone

  • Start making calls and text messages

How To Activate Vodafone SIM, Which Is Deactivated?

If you have a Vodafone Pay-as-you-go number, you need to activate it by using it at least once, such as sending a text or making a call every 180 days.

If you don’t use your Vodafone SIM for 3 months (90 days), Vodafone will send a text message that your account will expire, and there will be no activity for the next 3 months (90 days). After the 180-day period, your Vodafone SIM will no longer work.

Furthermore, if someone steals your phone or you lose it, and you fail to apply for a replacement SIM for 180 days, your existing SIM will disconnect. In that case, you need to get a replacement SIM and activate it through the above-mentioned methods.

You cannot activate a SIM that is deactivated online. You have to contact Vodafone to see if your SIM, MSISDN, and IMSI can be reactivated at all. This is because these settings can be assigned to somebody else if you fail to take any action for 180 days.

To reactive your Vodafone SIM:

  • Call Vodafone customer care or visit a Vodafone store
  • Submit the reactivation request
  • Provide valid proof of address and photo ID
  • Wait for the confirmation call to reactivate your number


We hope that this guide helped you fix the Vodafone SIM activation issue. If you are a Pay Monthly customer and your SIM is deactivated due to an unpaid bill, you can reactivate your SIM card by paying it.
