SIS File is basically a Symbian OS Installer File which is used to install any application on your mobile phone. They generally have the extension .sis or .sisx and can be installed on any mobile phone that runs on the Symbian operating system.
Their function is analogous to the operation of Win 32 executable (.exe) in Windows Operating System.
Usually when a Symbian application is made, a request is sent to SymbianSigned.com to authenticate and verify the application before it is publicly distributed. However in cases where the application remains Unsigned, it has then to be signed manually to your mobile IMEI in order to make it work or else your mobile will fail to install the application triggering a Certificate Error Warning.
In this post I am going to share a simple tutorial originally taught by Symbianv3 that will teach you How to Sign .sis files. It is important to know how to sign .sis files because many of the upcoming great applications like IR Remote, NokMote, RotateMe etc are being distributed unsigned over the Internet.
Things you will need to sign .sis files
- Registered and activated account at SymbianSigned.com
- Your Mobile IMEI number (Enter *#06# on your mobile)
- GenialSis application
Get started
- Open GenialSis.exe and enter your IMEI number. Press Generate! and you shall see a popup dialog saying Completed.

- Enter your SymbianSigned.com username and password in Step (2) and press Upload certificate.

now you will see a notice like

- Press OK and then select the genialcert.csr file in the GenialSis application folder.

- Enter security code and then go to step (3)
- Click Open and select the .sis file you want to get signed and then click Sign.

Thats it! Your unsigned application has now been signed can be used on your mobile.















Hi
nice post but the problem is they allow only ppl who have there own email id not free once.
This tool is helpful but may not benefit many.
Thnks for sharing
Good tut. Will need it in the future. Stumbled!
The SIS signing application needs .Net Framework installed.
Please can someone enlist the names of sites whose email addresses are allowed for registration on symbiansigned.com
Looks like, they accept .net email addresses as well. Just signed up with my work address.
Will check the application later and will update.
Go to http://87robert.webs.com to find software to sign SIS files your self. Its in the Nokia downloads section.
I have a @hotmail.com e-mail and I can’t create account on Symbian signed. Any solution about that?
No. You can’t sign with public e-mails like Yahoo, Gmail, Rediff and stuff like that…You have to give a private email id which you can create with a domain…eg. namecheap.com (just visit the site to find exactly what they mean). You can even register with your work/company email address or your Internet Service Provider email eg. something@vsnl.net etc
Basically the thing is that you should have a mail id which not common. It should be private.
Hi! I did everything what is written, I installed Nokmote to N95 and it couldn’t run that application, it writes nothing, please help me!
Hey guys use *****@testandtune.com for registering in SymbianSigned. It works.
http://signsis.webs.com/
Try the site above. It worked for me!
I have a valid username (email) and password in symbiansigned, but every time i use genisalsis to sign an application it doesn’t work, it says that i have exceeded my number of certificates allowed for production in 24 hrs, but i didn,t sign anything…can somebody help me??
Same here. any clue??
I had that problem two. Now I’am doing it at another PC.
Works for me only need framework 3.5.
i have the same thing i believe it’s because symbiansigned website is no longer allowing offline signing a solution to this would be appreciated
Hey I have a Nokia N95. They have open signed disabled for only people. Just like you and me only you can use it if you have a publisher id. And I am still looking for how now?
I can at last sign in SymbianSigned but I am having the same problem like “Nokia User” above. Please help!
I have a valid username (email) and password in SymbianSigned, but every time I use GenisalSis to sign an application it doesn’t work, it says that I have exceeded my number of certificates allowed for production in 24 hrs, but I didn’t sign anything…can somebody help me?
I have the same problem as above. Can anyone offer any assistance?
I get the same error…too many applications in 24 hours. whats the deal here? do symbian not want people to use the apps?
Same prob here…exeeded number of certificates :S
Guess this little trick doesn’t work anymore?
Unfortunatly this software failed to satisfy our need, simply because it keeps on showing that I have exceeded my number of certificates allowed for production in 24 hrs even though I am still a fresh user
same problem as nokia n95 user
Same here
Same as above, I have a valid user name/account at Symbiansigned and the first time I tried to use the Genial software the message is that I have exceeded the number of certificates allowed !
So it’s useless as the last 12 people had the same problem !
if anyone wants me to sign thier unsigned version of nokmote beta, i will sign for you i just need your imei and e-mail address, with £2 via paypal, e-mail me at nicktheparty at hot”mail (.) co (.) uk

“Failed request. You have probably exceeded the number of certificates allowed for production in 24h”
