What are the differences between the "Basic (MIDP 1)" and the "Advanced (MIDP 2)" versions?
The Advanced (MIDP 2) version uses more advanced text and image compression algorithms, reducing your waiting time and the amount of data transferred. It also offers more features like page icons, more font options, better-looking menus, smooth scrolling, a built-in clock, content folding and secure connections. See our
feature list for more details.
Advanced (MIDP 2) phones can often fit large Web pages in the phone's memory. In Basic (MIDP 1) phones, large pages are automatically divided into several partial pages. Please note also that latest version of is 3.1.2 and hence does not support Opera Mini latest features.
Advanced (MIDP 2) version
Basic (MIDP 1) version
You can easily see which version you have when you launch Opera Mini. The Advanced version will show you the Opera Mini logo, while the Basic version will only show you text.
What is the purpose of the screen where you need to press keys until the indicator is full?
To protect your communication with the Opera Mini server, the client needs to create a secret key. The key needs to be long enough so that it cannot be easily guessed or predicted. The best way to ensure that the key is not predictable is to use a random key. Opera Mini generates a random key for this purpose when you randomly press keys on the keypad until the indicator is full.
Where in my phone can I find Opera Mini after installing it?
Opera Mini will usually be filed under
Applications,
Java Applications,
File Manager or a similarly named folder that can be reached from the
main menu of your phone. Occasionally, it can be found under
Games — although this is typically on smaller, older phones. If you can’t find Opera Mini anywhere on your phone (and you are sure that you installed it correctly), please consult your mobile phone manual or your phone manufacturer’s Web site.
How to set permissions in signed versions of Opera Mini
As of Opera Mini 4.1, we will offer signed versions along with unsigned. The advantage of the signed version is that you can change permission settings to less restrictive permissions. The end result is that you will get fewer permission dialogs for e.g., file and network access.
How to set permissions for Opera Mini varies a lot among different phones, but we will give you a few examples:
- In general, you have to locate the folder where Opera Mini 4.1 is. Then you have to highlight Opera Mini 4.1 and press an options/menu button.
- Sony Ericsson: Highlight Opera Mini 4.1, click "More", then "Permissions". Here you can set "Read user data" and "Write user data" which are used by Opera Mini 4.1.
- Nokia (Series 40 3.0): Highlight Opera Mini 4.1, click "Options", then "App. access", then "Data access". Here you can edit "Read user data" and "Add and edit data" which are used by Opera Mini 4.1.
Do I need some kind of Internet service from my mobile provider?
In general, you will need to have some level of Internet access provided for in your phone service agreement. You need to check with your mobile provider if you have this included in your services.
What is JSR-75?
JSR-75 is a specification for Java applications such as Opera Mini to access device internal storage and functionality within the phone. Some of Opera Mini features like “Save Pages” and “Download/Upload Files” vary on how much JSR-75 that is supported by the phone. For more info on JSR, please see the
Wikipedia entry.
Using Opera Mini
Can Opera Mini 4 display Web pages as one vertical column?
Yes. Go to
Menu >
Tools >
Settings and choose “Mobile View”.
To scroll by page, use the
left and
right keys. To highlight links or to scroll quickly, use the
up and
down keys.
When using "small font", I can’t see special characters
It might happen that in some languages small fonts do not appear correctly. It has been improved a lot since version 4.2. You should now have a better support.
Some letters look like black boxes, and I don’t use the small font
Opera Mini uses the phone’s default font. If your phone doesn’t support certain characters (e.g. Chinese characters), then Opera Mini won’t support them either.
What is the difference between ‘http connection’ and ‘socket connection’?
If you choose to use
“socket connection”, Opera Mini will keep an open connection to the Opera Mini servers. This means that pages will load quicker, and the Opera Mini servers can push updates (for example new bookmarks through Opera Link) directly to Opera Mini on your phone.
If you choose
“http connection”, Opera Mini has to establish a connection to the Opera Mini servers every time you load a page. New updates to Opera Mini will also not be pushed to the phone until a new page is loaded. Note: not all phone models and mobile networks allow socket connections. If you have problems with your connection, try to use “http connection” instead.
Settings
What are the correct APN Internet settings for my phone (APN settings)?
To be able to connect Opera Mini to the Internet, your phone needs proper settings. In general, there are two different settings:
Opera Mini usually needs the Internet setting, and to use the
Internet APN. (What is an APN? Have a look on
Wikipedia.)
To help you get the right settings, we have created a
settings page for each phone model that Opera Mini is available for. Please click here to select your manufacturer or service provider, and then make sure to download and activate the correct settings for your phone.
How do I manually enter APN Internet settings on my phone?
Please consult your mobile phone manual or your phone manufacturer’s Web site.
I have the right settings, but Opera Mini still doesn’t work
There are devices that require a special configuration in addition to the right settings. Some Nokia phones require you to activate the settings as default in all applications. In addition, some Sony Ericsson phones require you to set the
Settings for Java.
Try our
settings page, and if that doesn’t help, please contact your service provider.
My settings are not in your overview, but they work!
If you have settings that we don’t have on our
settings page, please provide us with information using
this forum thread. It may take some time before the information reaches the official settings page, but it will!
How do I enter APN Internet settings on my Nokia Series 40 phone?
Starting from the point where you have already downloaded and installed Opera Mini, but you are unable to load pages:
- Go into Settings.
- Go into Configuration.
- Go into Personal Configuration Settings.
- Now, press Add New (visible if you don’t have a previous Personal Setting created) or press the Options button. When you have pressed the Options button, choose Add new.
- When you have pressed Add New, you will get a new menu, which will give several options to choose from.
- Now, scroll down and choose the Access Point and press Select. (Please note that this option is not available on the Nokia 3220 model and maybe on some more models, you can instead use the Services option instead of the Access Point option on the Nokia 3220.) Do not choose the Web option, since this will not work with Opera mini.
- Now go into Access Point Settings.
- Go into Bearer Settings.
- Go into Packet Data Access Point.
- Now, enter you APN address corresponding to your provider. Then press OK.
- Go back to the Personal Configurations Settings menu, where you now should be able to see an Access Point selected.
- Now press the Options button, and then choose to activate this Access Point.
- Now you should be able to start Opera Mini, and try to load a link on your phone.
If you are still having problems with your Nokia S40 2.0 model of phone, please make sure that you have entered all the required information into the APN setting concerning proxy, user name, password, port etc.
Security
Does Opera Mini support encrypted connections?
Yes. Information sent between your handset and the Web site is encrypted in the advanced version of Opera Mini 3.0 and newer versions.
In the basic version of Opera Mini 3.0, and in older versions, there is no encryption between your handset and the Opera Mini servers. See a more detailed explanation
here.
Is there any end-to-end security between my handset and — for example — paypal.com or my bank?
No. If you need full end-to-end encryption, you should use a full Web browser such as
Opera Mobile.
Opera Mini uses a transcoder server to translate HTML/CSS/JavaScript into a more compact format. It will also shrink any images to fit the screen of your handset. This translation step makes Opera Mini fast, small, and also very cheap to use. To be able to do this translation, the Opera Mini server needs to have access to the unencrypted version of the Web page. Therefore no end-to-end encryption between the client and the remote Web server is possible.
Can Opera Software see my passwords and credit card numbers in clear text? What is the encryption good for then?
The encryption is introduced to protect the communication from any third party between the client (the browser on your handset) and the Opera Mini transcoder server. If you do not trust Opera Software, make sure you do not use our application to enter any kind of sensitive information.
What cryptographic algorithms are used to protect the communication?
The communication is protected by 256 bit RC4 and the key exchange is done by 1280 bit RSA. All hashes are created using SHA-256. These are the algorithms used by most SSL sites today.
What do the different padlock icons mean?
The page is secure.
Parts of the page are secure, but some items contained within the page are not secure.
For more information on specific page from Opera Mini go to
Menu >
Tools >
Page information.
Why does the page information say that the connection is not secure when you said all traffic is encrypted?
All versions of Opera Mini support encryption between the Opera Mini server and any Web site. Starting with Opera Mini 3 Advanced, the connection between your phone and our server — the Opera Mini client and the Opera Mini Transcoder server — will always be protected by encryption.
Note that the encryption is only available in the advanced version of Opera Mini, and not in the basic version. In the basic version, and in older versions of Opera Mini, the connection between the Opera Mini client and the Opera Mini transcoder server will always be unencrypted. Parts of the connection may however still be encrypted depending on your provider and wireless protocol.
With older versions of Opera Mini, or Opera Mini 3 basic:
- The connection between your phone and the Internet Access Point may be encrypted by GSM, AMPS, TDMA, or CDMA.
- The connection between the access point and your provider’s internal network is possibly unencrypted, but it is not a public net.
- The traffic between your provider and the Opera Mini server is not secure.
- The connection between the Opera Mini server and the remote Web server is SSL-encrypted.
With the advanced version of Opera Mini 3 and higher, all of these connections are secure.
MIDP already supports secure sockets and HTTPS. Why invent your own solution instead of using the existing support?
Opera Mini runs on hundreds of different handset models. During development we found out that certificates and implementations of secure sockets/SSL is an area where there is little standardization, with many bugs and big differences between different handsets and manufacturers. This is the current state of J2ME/MIDP, so we found developing our own solution to be the only viable option.
How does Opera protect my privacy?
Opera does not store any users' private information. Opera generates statistics of the usage of Opera Mini, but these are aggregated numbers and no information can be linked to a single user.
All information gathered by Opera Mini is subject to Norwegian laws regarding personal data. More information about the Norwegian Personal Data Act and Regulations can be found
here.
What kind of data does Opera store on the server? Will filled-in data like credit card numbers be stored, or possibly cached?
No, the servers will not store any such data.
Why am I still logged into my Web mail even after turning off Opera Mini?
Opera Mini will never store your password on the servers. However, the Opera Mini server will keep track of any HTTP cookies that are set by any remote Web server. If you return to a Web page that has set a cookie to keep track of who you are, the Opera Mini server will submit it again.
How do I erase the cookies?
