The main problem of smartphones based on the Symbian operating system is the inability to install and / or run the application after the certificate expires. At the same time, the smartphone will honestly warn the owner with a system message. What is a certificate? In fact, this is a so-called "electronic document" that gives the application the right to be installed in the Symbian environment. This document is unique to each user.
In the first step, you need to obtain your personal certificate. A special key is included with the certificate. To obtain a certificate, you need to use the online service by visiting a special website (https://allnokia.ru/symb_cert/). In special forms, enter the IMEI of the phone (IMEI can be viewed by dialing the code * # 06 #) and the model. You can receive the certificate by e-mail or download it via a special link only after a certain time. Most often, the process of issuing a certificate takes 2 days.
Now you need to sign the application with a certificate. However, sometimes you need to remove the old certificate first. But usually this procedure can be avoided. A variety of applications can be used to renew a certificate.
The app is not available directly on the internet.
1. Find one of the sites that provides this opportunity. (https://www.symbiansigned.com/app/page/public/openSignedOnline.do).
2. Fill in the fields, indicating the phone's IMEI, real email address, in the Application field - select the application file that you want to sign, located on your computer. Below click Select all.
3. Now you need to enter the code shown in the figure.
4. Check the box next to Accept legal agreement. Click Sent.
5. A letter containing a link to confirm the transaction will be sent to your e-mail address. Follow it.
6. In the new letter that you will receive, there will be a link to download the signed application. Download it and install it on your smartphone.
To sign the application with a certificate on your computer, use the SISSigner application.

2. Attach the certificate and key file to the folder with the program that you installed.

The application signing procedure is not complicated, but it takes some time. Perhaps those who have a smartphone based on the Symbian operating system will not be able to do this right away.
