Why does it say my number is not connected to Swish?

Swish is tied to one phone number at one bank. If you changed number, changed bank, or closed the account Swish was linked to, you have to connect the number again. You do that in your bank app or online bank, and you approve it with BankID.

Can I undo a Swish sent to the wrong number?

No, a completed Swish cannot be stopped. Contact the recipient and ask for the money back, and call your bank to tell them what happened. That is why it is worth reading the name Swish shows you before you confirm, not just the digits.

Why is my Swish declined when there is money in the account?

Usually a limit. Banks set a cap per payment and per day for Swish, and you can normally change it yourself in the bank app. Also check which account Swish is linked to, because it is not always the one your salary goes into.

Swish is not working? Here is how to sort it out

Swish is the Swedish instant payment app that almost everyone here uses to send money between private people. It needs three things at once: internet, a valid BankID, and your phone number connected to Swish at your bank. When Swish plays up, it is usually BankID or the connected number, and both take a couple of minutes to check.

One rule that covers every payment: nobody legitimate ever asks for your BankID code or your password. Your bank, Swish, BankID and Solvora will never ask for a code. Never approve a BankID signing that you did not just start yourself, and never send money because someone rings and talks you through it while you do.

Try this first

Check that the phone has internet. Open any web page and see that it loads.
Open the BankID app. If you see your name in the list and can type your security code, BankID is fine. If not, fix BankID first, because Swish is built entirely on top of it.
Update both Swish and BankID. On iPhone in the App Store, on Android in Google Play. Search for the app name and tap Update if the button is there.
Restart the phone and try the payment again.
Check the balance of the account Swish is linked to. It is not always your main account. You can see which one it uses under Settings in Swish.
Check the recipient's number digit by digit, and read the name Swish shows you before you confirm. If the name does not match, stop there.

If that did not help

If it says the number is not connected: log in to your bank app or online bank and connect your phone number to Swish again. You approve it with BankID. This is always needed after a number change, and often after changing bank.
If the payment is declined with no explanation: check your limit in the bank app. Most banks have both a per payment limit and a daily limit, and you can usually raise them yourself. A raise can take up to a day to take effect.
If the app sits on a spinning circle: close Swish completely and open it again. On iPhone, swipe up from the bottom of the screen and flick the app away. On Android, tap the square or swipe up, then swipe the app away.
As a last step you can delete Swish and install it again. Your details stay with the bank, but you will need to connect the number again and approve with BankID. Leave this until the rest has been tried.

If something has already gone wrong

If money has left your account but the recipient has not received it, wait a few minutes and check the account in your bank app before sending again. Double payments usually happen when someone retries too quickly.

If you sent money to the wrong person, contact them and ask for it back, then call your bank and tell them what happened.

If you think someone has tricked you, call your bank immediately. Banks answer around the clock for blocking cards and accounts, and the number is on the back of your bank card and on the bank's website. Then report it to the police on 114 14. We can help you work out what happened and what to say, but only the bank can act on the money, so call them first.
