By selecting a graphic of a given size, you tell LOLA what kind of message you want to send.
It should be noted that the standard Nokia 9110 Communicator is only capable of receiving operator logos. Group graphics and Picture SMS are not supported by the phone side interface. Anyway, LOLA will detect such a message sent your phone and display it on the PDA side. You can then save the graphic to a file. This way, sending group graphics can also be used for wireless exchange of operator logos.
A few things have to be kept in mind when sending graphics:
- It is absolutely vital to send the messages through an SMS Center ("SMSC") that supports both 8-bit messages and the UDH (User Data Header) feature. Otherwise, the message will reach its destination as garbled text. Most networks are upgrading their centers to support these advanced options.
- When sending an operator logo, a cellular network must be specified. This is required because a logo is only displayed for one particular operator specified in the SMS. If you are roaming within another network, the logo will disappear. This means that you will have to select the network which the receiver of the message is currently booked into, regardless of your own network.
- To turn off the logo on a phone, select "Turn off operator logo" from the "Network" list and send any logo to the device.
- There is an added complexity when receiving a Picture SMS from a 3210 phone: due to a bug in earlier versions of the 9110's phone software (older than phone 5.06/PDA 6.08), these messages are not recognized and get discarded without notice. The only fix is to have your firmware updated by Nokia. Exchanging messages between 9110 phones works fine, though.
- A list of networks with their MCC/MNC code numbers as specified by the GSM standard is contained in the OPERATORS.CSV file installed in the "Own Texts" folder. You can add or remove entries in this file to customize the list of networks you are typically sending logos to. The DEFAULT.NOL file contains a logo or group graphic that will be loaded when LOLA is first started up. If you want to modify either of these files, you have to do it on the PC and then install an updated version of the software on the phone.
