Do I need 3G/4G on my tablet?


Do I need 3G/4G on my tablet?

Most tablet manufacturers (except Amazon Kindle) offer either Wifi or Wifi plus 3G/4G options. Wifi access is available in most homes, offices as well as in most coffee shops worldwide generally for free or for a nominal fee. In my last 18 months of owning a tablet, there have been few days when I wished 3G was available on my tablet for few hours of long drive. You can read books, most magazines on flipboard and even email even without connectivity by caching part of these files before leaving the house.
With 3G/4G connectivity, your tablet can always be connected (subject to availability of 3G/4G connectivity from your mobile operator) to the Internet. However, unlike smartphones, tablets are not generally used on the go and so having always on connectivity just doesn't offer the same benefits for the cost incurred. So if you need 3G/4G connectivity there are other options besides owning a tablet with such a capability for lot lower price.

Getting a 3G/4G tablet will cost you over $600 for 2 years

Most tablets cost about $100 or more for including the 3G/4G options in addition to Wifi which is standard on most tablets. For most Android tablets, many mobile operators offer a discounted price for a 2 year contract. I looked at some of the tablets at T-Mobile and AT&T stores and saw that for an initial discount of about $200, you end up committing to an additional cost of $960 for T-Mobile, $840 for AT&T and $720 for Verizon Wireless. So the discount of $200-$300 upfront ends up costing you an additional $100 on the price of the tablet plus $500+ of extra cost for getting that 3G/4G connectivity which you could get much cheaper in other ways.
For Apple's iPad, no mobile operator offers any discount upfront but the tablet ends up costing $130 more plus you pay a minimum of $15/month (250MB) to AT&T or $20/month (1GB) to Sprint or $30/month to Verizon (2GB).

If you have a Wifi tablet and are not in the Wifi zone, there are two choices available for getting your tablet hooked up to the Internet.


How to get always on-connectivity on your tablet without buying 3G/4G tablet

  • Get a mobile hotspot
  • Get Tethering option on your smartphone

Get a mobile hotspot

This could actually get expensive as the data charges are similar to that of the tablet. However, this alternative is only beneficial if you have a need to connect your laptop to the Internet all the time for the same reason you need to connect your tablet.

Get Tethering option on your smartphone

This option, available on most Android, Blackberry and iPhone models, allows you to turn your smartphone into a mobile hotspot. With this option, you can have 5 devices including your tablet and laptop connect to the Internet. The good news is that this option can be turned on and off on most mobile networks in the US. Sprint charges only $10/mo extra for this option while other mobile operators including AT&T and Verizon charge $20/mo. The only negative of this option is the battery drain that your smartphone will experience.
3G/4G connectivity is generally not needed on most tablets. If needed, don't buy this from your mobile operator as it will set you back by $600 on a 2-year contract despite initial $200-$300 discount. If you need to connect your tablet to the Internet all the time, look at using your existing mobile hotspot or just add tethering option on your smartphone which will save you money and won't lock you into a contract.

Why you may never need a new mobile phone

The mobile phone that a Danish firm hopes will last for ever.
Some things, such as furniture or jewellery, are made to last a lifetime – yet despite being equally pricey, it is hard to find an electronic gadget that can hope to outlive a goldfish. Mobile phones are usually upgraded every few years, and there are few personal computers that aren't riddled with viruses or just plain knackered after a decade.

But now a counter-movement to technological disposability is emerging, promising electronics that can last for ever. Leading the charge is Danish firm Æsir, which claims to have invented a mobile phone that will never need to be replaced. It has a pared-down design carved out of surgical-grade steel. "There's a long tradition in Denmark to build things that will last," says Thomas Møller Jensen, Æsir's founder. "So we tried to design our mobile phone like you would a chair, boiling it down to the essence of what it should be."

And it turns out that the essence of a mobile phone … is a phone. Æsir's device does little more than make calls and send texts, like a luxury watch that only tells the time (and like a luxury watch, it costs €6,000/ £5,200). It is proof, though, that simplicity is the key to longevity.

Despite having the sophistication of a pocket calculator, for example, Pac-Man has remained one of the world's most popular video games for 30 years. And Amazon's Kindle comes closer than any multifunctional tablet computer to achieving lifelong appeal by sticking to the basic job of displaying books.

Everlasting gadgets, however, need tough hardware. In the future, science may provide us with machines that don't wear out. This year, researchers at the Fraunhofer Institute for Environmental, Safety and Energy Technology in Germany unveiled a plastic that heals itself like skin, while Australian researchers have shown it is possible to design batteries that never need recharging.

Jensen, whose favorite gadgets include his 20-year-old handbuilt turntable, believes that consumers and manufacturers must first change the way they think about electronics. "There's an obsession with obsolescence. I'm sick of opening the newspaper and having adverts for 200 new televisions in my face," he says.
