20 Most Recent Siemens A51 Questions & Answers

If the carrier that originally locked your Siemens C25 is defunct and you can't get the unlock code from them, there are a few other options you can try:

1. Use a third-party unlocking service: There are many online companies that offer unlocking services for mobile phones, including older models like the Siemens C25. You'll need to provide them with your phone's IMEI number and pay a fee for the service, but they can usually unlock your phone within a few days.
2. Try unlocking the phone yourself: If you're technically inclined, you can try unlocking the phone yourself using software tools and a data cable. There are many guides and tutorials available online that can help you with this process, but be aware that it can be risky and may void your phone's warranty.
3. Use the phone on a compatible network: If all else fails, you may be able to use the phone on a compatible network even if it is still locked. Check with local carriers in your area to see if they support the Siemens C25 and if they can provide you with a SIM card that will work with the phone.

There is no 'master code'. The code is based on that phone's IMEI number. There are companies that will sell you the code for your phone. If your telco locked it, no one can open apart from them. They do that so stolen phones can't be used. https://www.google.com/search?q=code+for+a+siemens+S45 ..

If you can identify the current language setting, you can try an on-line translator of the menu items to determine which one is for language settings. Alternatively, you can download the user manual for your appliance and look up the language change procedure there. The menu items are almost certainly arranged in the same order in any language, so it would be a matter of keeping track of where you are in the process. http://www.siemens-home.bsh-group.com/uk/customer-service/user-manuals
