A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio.
Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1200 and 2400 bit/s for asynchronous dial connections, 4800 bit/s for synchronous leased line connections and 35 kbit/s for synchronous conditioned leased lines were available. By the 1980s, less expensive 1200 and 2400 bit/s dialup modems were being released, and modems working on radio and other systems were available. As device sophistication grew rapidly in the late 1990s, telephone-based modems quickly exhausted the available bandwidth, reaching the ultimate standard of 56 kbit/s.
The rise of public use of the internet during the late 1990s led to demands for much higher performance, leading to the move away from audio-based systems to entirely new encodings on cable television lines and short-range signals in subcarriers on telephone lines. The move to cellular telephones, especially in the late 1990s and the emergence of smartphones in the 2000s led to the development of ever-faster radio-based systems. Today, modems are ubiquitous and largely invisible, included in almost every mobile computing device in one form or another, and generally capable of speeds on the order of tens or hundreds of megabytes per second.

Niloadan ko dito simcard ko at nakainsert sa Black Mamba openline modem, properly set naman ang Dito APN, connected sa portal pero no browse.
May known issue ba talaga sa dito simcard na naka insert sa modem? Pano to gawan ng paraan mga lods salamat!
Bigla ko lang naisip, namali kasi ako ng bili ng no expiry data para sa sim ko sa modem.
nabili ko ang no expiry data with call minutes instead na data lang.
Tanong ko lang: Meron kaya app sa pc na pwede gamitin para magamit ang minutes ng sim sa modem na no need na ireinsert sa phone?
di ba nababypass natin yung gowatch na yung ang magamit pag nagbbrowse tayo gamit http injector or ibang vpn na pwede. possible rin kaya yon sa modem? i mean sa modem na sya mismo, sa may vpn section. pwede rin kasi gumamit ng injector kapag naka connect ka na sa wifi pero mas maganda lang...
