Accessing the Internet through the cellular phone or a PDA is not going to be the same experience as browsing the web on your habitual computer. Some of the drawbacks of Mobile Net are as follows:
The screen video display sizes of cellular telephones and PDAs are really small and it can be problematic viewing text and graphics implied for common computer screens. In this regard, PDAs are a better bet than cellphones, and laptops, of course, don't face this matter.
1. Typing out large entries using small keypads is an inconvenient process. Acquiring keyboards that fold open may be accommodating here. But then again there may be a character limit on the messages you can send.
2. You may find it troublesome or out of the question to view PDFs, Flash sites and video sites.
3. You can view only one window at a time on cellular telephones and PDAs and scroll just up and down.
4. The Mobile Internet connexion may be very slow counting on your distance to the nearest aerial.
5. You can't view regular websites in the format they are meant to be viewed.
Mobile Internet Serving
The standards for mobile Cyberspaces service are:
WAP: WAP is short for Wireless Access Protocol. WAP enables Internet access through your mobile devices and makes it possible to use synergistic data applications programmes on them.

CDMA: CDMA stands for Code Division Multiple Access. With CDMA technology, information is transferred through different channels not just one like with GSM.
EDGE: EDGE stands for Enhanced Data rates for GSM Evolution. It is also known as Enhanced GPRS or EGPRS. EDGE has better data transmitting values than GPRS and the data transmittance reliability is higher too. This is a wider choice for multimedia applications.
3G
Global Mobile Telecommunications-2000 (IMT-2000), better known as 3G or 3rd Generation, is a family of standards for mobile telecommunications implementing specs by the International Telecommunication Union, which includes UMTS, and CDMA2000 as well as the non-mobile wireless standards DECT and WiMAX. While the GSM EDGE standard also satisfies the IMT-2000 specification, EDGE phones are typically not branded 3G. Services include wide-area wireless voice telephony, video calls, and wireless data, all in a mobile surroundings. Equated to 2G and 2.5G services, 3G allows simultaneous use of speech and data services and higher data rates (at least 200 kbit/s peak bit rate to fulfill to IMT-2000 specification). Today's 3G systems can in practise offer up to 14.0 Mbit/s on the down-link and 5.8 Mbit/s on the uplink.
GPRS
General packet radio service (GPRS) is a packet directed mobile data function accessible to users of the 2G cellular communicating systems international system for mobile communications (GSM), as well as in the 3G systems. In 2G systems, GPRS provides data rates of 56-114 kbit/s
