Don’t get me wrong. I love being able to communicate textually with friends, coworkers and family. It’s ideal for a noisy pub; a somewhat-private conversation on a crowded bus; telling something to someone who may be asleep, so they see it first thing when they wake up; making quick responses while in a meeting without being rude (well, at least at my workplace it’s considered perfectly acceptable). It’s also very handy when you want to tell someone something they ought to write down, such as a phone number or something they should remember to buy. My problem isn’t with the concept of mobile textual messaging - it’s with SMS, the “Short Message Service”, as provided by Israeli carriers (and possibly worldwide).
The first problem I’d like to discuss is length. SMS messages are limited to 160 characters, or rather - 160 bytes. If your message includes any foreign characters, such as Hebrew letters, then UTF-16 mode takes effect, and your message is limited to 70 characters, which is ridiculously short. While the name of the service, SMS, implies that the messages should indeed be short, this is not the only common usage: If you want to have an actual conversation with someone (and this is a perfectly reasonable situation), messages will be longer than 160 characters, and certainly longer than 70. The problem becomes worse if u dont want to use shorthands n skip punctuations like many smsers do. (Ever found yourself about to send a 75-character message, going over it to find 5 characters to trim without looking like an idiot?)
There have been several attempts to overcome the short-message problem, all of them implemented as workarounds in cellphone software. The initial, primitive approach was to simply split a message up into appropriately-sized chunks, and send out those chunks as separate messages: A 150-character Hebrew message would be sent out as 3 separate messages (70, 70, 10 characters respectively). Later on, a mechanism was invented for the phones to detect the split messages, stitch them back up on the recipient’s phone, and notify the recipient if the message is incomplete. Poor man’s TCP.
The split-message solution is very problematic, especially when taking into account two other problems with SMS: Reliability and price. The reliability problem is subtle: SMS message usually make it across, but when they don’t (and sometimes, in fact, they don’t), no notification is given. Where E-mail servers notify you about delivery failure, where instant messaging services tell you that the other party has disconnected, SMS has… nothing. There’s no way to know that your message hasn’t been received, unless a little-known, not-supported-everywhere and highly annoying “read receipt” feature is enabled.
The price problem is completely absurd: I have a small 1GB plan at Orange, which costs 70₪/month. That’s 70 NIS / 1GB, 1GB being 109 bytes. That comes to 7 × 10-6 Agorot per byte. Suppose that an SMS-style service would need a bloated 100-byte header, so an SMS message is 260 bytes. Therefore, an SMS message should cost 0.00182 Agorot. In reality, it costs 44 Agorot (inter-carrier average) without a plan, or 14 Agorot (at best, requiring a 1000-SMS plan) with a plan. That’s between 7692× and 24176× as much.
One additional problem with SMS is the fact that they’re locked into your device. Got a new phone? You have to go through a very complicated process to transfer your SMS messages over, and this isn’t possible for every phone. Lost your old phone? Unless you were backing up manually, your messages are gone. Have a separate work-phone? You’ll need to use each phone to see messages sent specifically to it. None of these problems occur with an online E-mail provider, why should they happen with mobile texting?
With modern phones, sending and receiving E-mail is just as easy as sending and receiving SMS messages. The main problem is that not everyone has a modern phone, and E-mail on older phones is quite cumbersome. Worse yet, older phones don’t immediately notify you of E-mails. There could be some good money in creating an E-mail-to-SMS gateway - and it would be quite convenient to use if done properly. Imagine having your SMS messages united with your E-mails, organized and searchable by your favorite E-mail client. If you have a modern phone with proper E-mail notification and sending abilities, this could be very handy. Just sayin’.
Addendum: It seems that Google Voice already does exactly what I want, but is not available in Israel. Thanks, Shachar.
