Things to keep in mind while using mobile phones

  1. Buy a branded phone.
  2. Ensure that the phone has a proper IMEI number, which is a code that identifies each phone. Check that the number on the phone corresponds to that on the box and receipts.
  3. It is considered wise to check the accessories such as earphones, battery and charger.
  4. Make sure the battery description such as voltage value matches with that of the charger to avoid overcharging which sometimes lead to explosion of handset.
  5. Avoid using the phone while the battery is being charged. If you wish to receive a call during this time, disconnect the phone from charger before connecting the call.
  6. Ensure it is not over-charged by removing the electric supply when the battery is fully charged.
  7. If your battery seems to have swollen, replace it immediately.
  8. The anti-virus software for mobile phones are not very effective today. That is why one should avoid downloading anything from a third party vendor, ie directly from the internet browser. Instead use the in-built store or market application provided by the operating system.
  9. Malware, which is software that takes advantage of a bug in the operating system of the phone, often gets downloaded with third party tools.
  10. Make sure the sites that you visit using the phone must start with an https (which means they are encrypted or safe sites).
  11. Avoid using public or unsecured Wi-Fi connections. A hacker could access the mobile device through a port that is not secured.
  12. Make sure the Bluetooth connectivity is not switched on in public places as it can be used to send malicious files which corrupt the operating system.
  13. While communicating using your cell phone, try to keep the cell phone away from the body as this would reduce the strength of the electromagnetic field of the radiations.
  14. Whenever possible, use the speaker-phone mode or a wireless blue tooth headset. For long conversations, use a landline phone.
  15. Avoid carrying your cell phone on your body at all times. Do not keep it near your body at night such as under pillow or a bedside table, particularly if pregnant. You can also put it on 'flight' or 'offline' mode, which stops electromagnetic emissions.
  16. Avoid using your cell phone when signal is weak or when moving at high speed, such as in car or train.
  17. If your phone gets wet, dismantle it by removing battery, SIM and memory cards and switch it off (only SIM card in case of an iPhone). Dry each component thoroughly (but gently) with a towel until the phone is dry to the touch. Avoid using it for 12 โ€“ 24 hrs and put it in a bowl that contains silica gel packets during that time to demoisturize it.
  18. Never use a hair dryer to dry the phone quicker.
  19. Avoid using mobile phones too close to your mouth regularly or holding cell phone in your mouth frequently. This might lead to malignant salivary gland cancer and tumours in the mouth. (There is no conclusive evidence that mobile phones are safe and don't cause cancer).
  20. Regular cell phone users who speak with the phone held too close to the face are prone to problems like sleep disturbance, migraine and headache.
