Your new 50+mobiel SIM card has arrived. Great — but how do you actually get it working? That depends on your situation: are you keeping your current number, or starting fresh with a new one?

In this article you'll find out exactly when you can activate, which steps to follow and what to watch out for. You'll be online within minutes.

When can you activate your 50+mobiel SIM card?

The timing depends on the choice you made when signing up:

  • Number porting: activate only on the transfer date you received via SMS. If you do it earlier, your old number won't work yet.
  • New number: activate as soon as the SIM card arrives.

Note: if you don't do anything within 14 days of ordering, 50+mobiel will activate the SIM card automatically. Handy as a backup, but you have more control if you do it yourself.

Check your payment first

Before you activate: make sure the first payment went through. Paying via direct debit? Then you don't need to do anything — activation will proceed normally. Did you pay manually (iDEAL, credit card)? Check your My 50+ account to confirm the payment has been processed.

Step by step: activating with number porting

You're bringing your current number to 50+mobiel. Here's how it works:

  1. Wait for the transfer date. This date is in the SMS you received shortly after ordering. Activate earlier? Your old SIM stays active and the new one won't work yet.
  2. Confirm receipt of the SIM card. Do this via your My 50+ account, or click the link in the email 'Your SIM card is on its way'.
  3. Turn off your phone completely. Not airplane mode — actually power it down.
  4. Swap the SIM cards. Remove your old SIM and insert the 50+mobiel SIM. You'll usually need a SIM ejector tool (often included) or a paperclip.
  5. Turn your phone back on. The 50+mobiel SIM doesn't ask for a PIN code — that's normal.

Your phone will now search for the 50+mobiel network. This can take a minute. Once you see '50+' at the top of your screen, you're connected. WhatsApp, calls, internet — everything works as you're used to.

Not sure if everything went smoothly? Send a test message or open Google Maps. Does it work? Then you're all set.

Porting a prepaid number? This can be faster

Currently using a prepaid number (for example from Lebara or Lyca)? You can often move the transfer date forward. Call 50+mobiel customer service for this: 088 228 2288. Available on weekdays from 09:00 to 20:00 and on Saturdays from 10:00 to 15:00.

Step by step: activating with a new number

You're starting with a new phone number. The steps are a bit simpler:

  1. Confirm receipt of the SIM card. Do this via your My 50+ account, or click the link in the email 'Your SIM card is on its way'.
  2. Turn off your phone completely.
  3. Swap the SIM cards. Old one out, new one in.
  4. Turn your phone back on. Again: no PIN code needed.

Your phone will now connect to the 50+mobiel network. See '50+' at the top of your screen? You're done. Your new number is in your My 50+ account and in the welcome SMS you'll receive.

Tip: activate online first, then insert in your phone

Want to speed up the process? First confirm receipt of your SIM card via your account or the email link. Only then insert the SIM card in your phone. This way the network doesn't have to wait for the online confirmation and you'll be connected faster.
