The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
A hybrid mobile phone can take more than one SIM card, even of different types. The SIM and RUIM cards can be mixed together, and some phones also support three or four SIMs. [15] [16] From 2010 onwards they became popular in India and Indonesia and other emerging markets, [17] attributed to the desire to obtain the lowest on-net calling rate.

This can occur at any time while a phone is turned on.
Without knowing exactly how the attackers modified the pagers, it is hard to know for sure that our consumer devices are safe. But experts advise that there is no need to worry.

We'll start with a couple of possibly mind-blowing tips: Stop charging your battery to 100% once a day and closing or refreshing idle apps.
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
Another common reason is when a phone is taken into an area where wireless communication is unavailable, interrupted, interfered with, or jammed. From the network's perspective, this is the same as the mobile moving out of the coverage area. Occasionally, calls are dropped upon handoff between cells within the same provider's network.
