Is sim.de down right now?
Going by current reports, sim.de works for most people right now. The live sim.de status on this page updates with each user report. A sharp rise in sim.de down reports means the trouble is service wide.
A single failed login proves little on its own. Forgotten passwords and locked SIM cards look like outages from the outside, so run the checks below before you wait for a fix.
Is sim.de down for me or everyone?
Try to open sim.de on a second device or ask another customer. If the portal loads there, the is sim.de down for me answer is your own login data or your app, not the platform.
Where does the Servicewelt hide my PIN and PUK?
Your PIN and PUK sit in the portal under your customer data, not on any letter alone. Many users search the app first and miss the entry, because the app shows only part of the SIM data.
After three wrong PIN entries the SIM locks and asks for the PUK. Users then rush to the portal, and a slow portal at that moment feels like a second fault on top.
Why does the password reset for sim.de fail?
The reset flow needs the right mix of user name and Servicewelt password data. Old saved passwords in the browser break the flow most often, because the form sends the stale entry again and again.
How do I order a replacement SIM in the Servicewelt?
You order a replacement SIM in the Servicewelt under your SIM and tariff area. Pick the replacement card or the eSIM, confirm the order, and the new card ships to your saved address. The eSIM path sends a profile with a code you scan into the phone. Your old SIM dies when the new one turns active, so order when you can swap at once. An eSIM profile that lands by mail first is the normal path, not a sim.de outage.
Why does the app lose my saved login?
The app offers an auto login, but updates and cache clears wipe the saved data. After that the app asks for full login data that many users no longer have at hand.
Common sim.de Problems and Fixes
These sim.de steps sort the portal login, the PIN and PUK search, and the reset flow that fails for most users.
Find PIN and PUK under customer data
Sign in to the Servicewelt and open your customer data. PIN and PUK are listed there for each SIM. You get ten tries for the PUK, so type it with care.
Type the password by hand once
Delete the saved password in your browser and type the Servicewelt password by hand. Saved old entries are the top cause of reset and login loops on sim.de. Dutch Simpel users hit the same loop when an old saved password survives an update.
Turn auto login off and on again
If the app opens the wrong account or forgets you, switch auto login off, sign in by hand, and switch it back on. That rebuilds the saved login on your phone.
Order the eSIM in the browser portal
The eSIM and replacement SIM orders sit under Services in the Servicewelt. If the app order hangs, run the same order in the browser portal, where it completes more often.
Wait before a second reset request
Each new reset kills the link or code from the last one. Ask once, wait for the mail, and check spam before you start the flow again.

Frequently Asked Questions
Why is my SIM locked and where is the PUK?
Three wrong PIN entries lock the SIM, and the PUK opens it again. You find PIN and PUK in the Servicewelt under your customer data.
How many tries do I get for the PUK?
You get ten tries for the PUK. After the last wrong try the SIM dies for good, so copy the code from the portal with care.
Is the Servicewelt password the same as my PIN?
No. The password guards your portal login, while PIN and PUK guard the SIM card itself. The portal shows both, but they are separate codes.
Does the app stay signed in on its own?
It can, with auto login switched on. Updates and cache clears wipe that saved login, so keep your password somewhere safe for the next full sign-in.
Can I switch to an eSIM in the portal?
Yes. The Servicewelt offers an eSIM order under Services, and the same path orders a classic replacement SIM. The app flow hangs at times, so the browser portal is the safer route.
What should I do when the reset mail never comes?
Check spam first, then wait a few minutes before a second request. A new request kills the first link, so fast repeats keep the account locked.
