To Pad or Not to Pad

A plethora of devices on the market make even those of us who have had a smart phone for several years uncertain whether to invest into something different. Here at B.A. Computer Services we endeavor to research everyday technical solutions and provide very practical advice (albeit not purely scientific) about our findings.

Clearly dissatisfaction or breakage of a current device is the impetus for shopping for another device. Modern communication, namely, texting, has not, and likely will never fully trump basic verbal communication–frequently over a phone device of some sort. Thus priority #1–Buy a PHONE. If you end up with a device that has great color, bells, whistles, and dances on the table, that cannot be easily picked up to make or take a phone call, you have been misled. Look first at your primary communication need–choose a device that you can answer easily, hear clearly, and that has a good microphone so the other party can hear you clearly as well.

Smart phones are a hybrid between a computer and a phone, er, camera, er, clock, er, stereo, er…pad. In other words, smart phones have become so ubiquitous and versatile it is unlikely they will fade anytime soon. The trouble is, any one device is still physically limited to time and space, so Dad’s phone just won’t suit being used as Mom’s ebook, Johnnie’s gamebox, and Suzie’s music all at the same time. Not only that, but Dad wants to be able to answer his calls and check stock quotes at the same time–that is a neat trick that technically is possible if you can tolerate hearing voices over a cellular speaker phone along with the dog barking, outdoor road noise, and kids arguing in the other room.

…the most subtle disadvantage to tablets is the difficulty to hold them without accidentally touching a part of the screen…

This, then, is where a search for a secondary device leads toward the possibility of purchasing a pad or an ipad if you are an Apple lover. Before you do, here are some gotchas you might consider. First, any secondary device means one more thing to tote around, charge, and remember to have on hand at the moment you need it. Having two devices can be twice the hassle as having one. Trying to fit a tablet into your back pocket simply doesn’t quite do the trick, and is a sure way to break the screen.

Yet, perhaps the most subtle disadvantage to tablets is the difficulty to hold them without accidentally touching a part of the screen. Holding a 6×8″ pad up to one’s ear is simply quite awkward. The truth about tablets is, they are not convenient as phones. The truth about smart phones is, they are trying to be too much to too many people. The best thing to do with these devices is to primarily designate them for limited use. Park your pad in one place and use it for a specific purpose. (Your electronic tablet I mean:-) Keep your smart phone in its usual pocket and avoid using it for other non-essentials. An old phone can of course be designated for children or an alarm clock, or whatever app you desire to install on it over WiFi. (In the case of a clock, plug it in permanently, prop at just the right angle, and leave it alone.)

The decision to purchase a pad, in lieu of or in addition to your phone, is yours and yours alone. While B.A.’s repairs these devices, we do not currently sell any of them. We are more interested in helping our customers with making smart purchases. Unfortunately, the old adage, “You get what you pay for,” can be misleading in the purchase of phones. Many higher-end devices are more expensive because of branding more than because of improved quality. Truly, any device with glass on its face that is carried around will eventually break. Buy what you really need, and when you need service, we are here to help. We can also install those perfect apps to recommission your old phone into something useful.

Solutions to Poor Cellular Service (Lake Fork, Lake Tawakoni)

Its Simple

GSM works far better than CDMA for one simple reason — the broadcast band it uses is more reliable. Nonetheless, among those that tout they use GSM, AT&T (prepaid counterpart Cricket) and T-Mobile (prepaid counterpart MetroPCS), T-Mobile/MetroPCS dropped service repeatedly in recent tests.   MetroPCS uses IP6 addressing over T-Mobile’s network. Verizon, despite their use of CDMA,  works well in most areas.

It would be hard to generalize, but in actual tests around the East Texas Lake Areas, MetroPCS phones dropped everything from cell service, to texts, to data during cloudy days.  Sprint phones and its counterpart Boost Mobile are expected to perform equally poorly in outlying East Texas areas.  While AT&T and Cricket might be better alternatives in some cases, there is always an expense trade-off.  Data plans vary between these companies but the main advantage any company will have over another is, up-time percentage:  Weather sometimes interrupts service–but a few clouds should not drop service entirely for any noticeable length of time.

A Little More

A feature of some cellular services is the routing of calls and texts over the same bandwidth as its data stream.  This means very annoyingly–no data access also means no texting.   GSM uses two different bandwidths, one for calls and texts, and the other for data.  This means you might temporarily hit a spot where you are without data (maps, music, web browsing), but your phone and texts will still generally work.  Photos sent via text do not actually go via text–because by definition texting is, well, text.  Thus, pictures always use data as multimedia or email messages, and may not go out at all in areas with poor service.

Here is a table extracted from https://techspirited.com/gsm-vs-cdma comparing GSM and CDMA technology. I have added a column to weight for usefulness in sparsely populated Rains County and adjacent rural areas.

Why Can’t I Bring My Phone to a New Carrier?

The cellular carriers are competing by using different technologies to market their version of the cellular services.  For example, AT&T  uses a protocol called GSM, while Sprint uses CDMA.  Technology is quickly changing, but for the most part, CDMA phones are permanently tied to the carrier from which they were purchased.  GSM phones however, are the type that have a removable card that can be swapped out to switch carriers to another GSM compatible carrier.  A few carriers are crossover carriers, meaning they support to some extent both GSM and CDMA phones.

The reason a company is offering you a free phone to switch from your existing carrier is that they know that the phone you have is likely not compatible with their network, and that the free phone you are about to receive from them is not compatible with your current carrier either.  Thus the free phone will be permanently tied to their service, a strong incentive for you to remain loyal to them.  This may not however be a big issue for a prepaid service. The phone was free and thus effectively dispensable. The data on the phone can be backed up (synced) to an Internet-based email account before you disconnect it, and when you get a new phone on a new carrier, you simply reconnect to that same email account and presto, all your apps and contacts are back.

Another common error in shopping for a phone, is that the marketeers are not just trying to sell you a phone, they are pushing camera sales.  A smart phone is not in the same paradigm as a traditional landline phone, which only permitted talking to people.  Smart phones are camera-video_recorder-stereo-phone-and-more all built into one small device.  Some of the features are incidental to the device (a speaker phone for example), while many features being pushed are non-essential (a camera isn’t needed to talk on a phone).  Thus the difference in price is all about the non-essential features you may or may not need.  If it is a phone at all, it will do the basic–it will allow you to make and receive calls.

So the next time you buy a phone with a carrier, just remember, you are effectively buying a disposable device that is locked to that carrier.  If you buy a more expensive smart phone with spicy features, realize you bought a camera more than you bought a phone and someday you may want to switch phone carriers and find out that your smart camera is not compatible with the phone carrier you want.  And yes, you can continue to use your smart camera without phone service, if that is what you want to do, but you willneed to periodically connect your device to a computer to extract the images since it will no longer be automatically backing all that stuff up to the Internet via a cellular connection.

The Future of Bluetooth

Personal experience with bluetooth technology has been less than satisfying for many.  Sometimes it works, and sometimes it doesn’t.  When it works, it works well. When it doesn’t work, well, it can be real frustrating.  Try out this recent article on one of the major phone manufacturers to see how they may be improving the technology soon.

For the newbies: What is bluetooth?  It is a technology that allows a device such as a mobile phone to be paired with a separate nearby device, usually a speaker or other sound system, to project the audio from your phone to the larger system (or a wire-free headphone set).  Projecting an MP3 collection downloaded to a cell phone, for instance, into an automobile’s speaker systems is one such use.  Hands-free telephone use is another application.
