CROSSCALL mobiles and smartphones comply with the IP67 or 68 standard which ensures total resistance to dust and liquids, for temporary or prolonged periods depending on the terminal and under normal use as recommended by the manufacturer. All our models have undergone strenuous waterproof and resistance tests to comply with these standards.

It’s very probable that your caller’s number has been saved in the 06xxxxxxxx format whereas the number calling is in the international +336xxxxxxxx format (or vice-versa). Simply save the number in the appropriate format.

As our mobiles and smartphones are waterproof and also very often airtight, closing the battery cover may cause overpressure inside the phone. This overpressure can affect the membranes of the earpiece, microphone and speaker, reducing the amplitude of vibrations and the quality and amplitude of the sound. The solution is to open the USB/Jack Plug cover at least once, once you have closed the battery cover, to release the “overpressure” inside the phone.

Depending on your model, the code is either “0000” or “1234”.

Just select the APN settings of your operator. Here is the way to proceed on our various models:


Discovery : Menu >> Messages >> 9 Message Parameter >> 2 Multimedia Message >> 1 Data Account, then select your operator.

Trendy : Menu >> Messages >> 8 Message Settings >> 2 Multimedia Message >> 1 Data Account, then select your operator.

Shark V2 : Menu >> Messages 8 >> Message Settings >> 2 Multimedia Message >>1 Data Account, then select your operator.

We suggest you restore the factory settings of your phone by going to Menu / Settings / Restore factory settings / press 0000 / Restore settings and turn phone on again? We would additionally advise you to insert an SD card to provide extra memory.

Withholding a number is a parameter that depends on your operator. Dial “#31#” to activate or deactivate this option.

You can take another call by pressing the “Call” (green key) key on your mobile. To shift from Call#1 to Call#2, press the “Call’ key, as with most mobiles on the market. End the call by pressing the “End Call” key (Red key)

The Shark Bluetooth is version 2.1. This version does not include automatic reconnection initiated from your mobile. Our tests have shown that automatic reconnection initiated by a vehicle’s Bluetooth system works correctly (if the phone’s Bluetooth is activated). The vehicle’s Bluetooth equipment should be a recent version which has the automatic Bluetooth scan and search function. If this is not the case, reconnection between the vehicle and your mobile will need to be done manually from your mobile or vehicle.

To withhold or display your number, go to the telephone application then to the menu via the key below and to the left of the display: Settings >> Voice call >> Other settings >> Caller number
