Excellent phone to date. Purchased from Public Mobile. Sound quality (both earpiece and microphone) is great as is reception. Features are limited but to be expected as this model is not a true smartphone, and nor is it intended as such. For essential talking and texting, the R312 is reliable and highly affordable. The Samsung name and quality also inspires more confidence than other brands carried by Public Mobile. Battery life may be slightly less than the 250 hrs (standby) stated by Samsung, but that is a small negative given the phone's positives. Would highly recommend. Less

Simple Little Phone

This Samsung R312 is a good, simple, flip phone which I highly recommend if you are more of a talker then a Text'er. I picked this phone up from Public Mobile last week and I already like it better then my old fancy old QWERTY phone with Virgin Mobile. Lets face it, on some level when we buy a phone most of us intent to make a purchase based on a need to talk on the go as primary function. Here is why I think this simple clam shell flip phone can be a better tool then some recent popular bulky options. (1) People have told me how good I sound on it which is nice, I suspect this might be due to the design length and arc of the R312 flip phone spanning the distance from ear to mouth compared to shorter and straighter phones that don't make it as close to the mouth. (2)The Speaker phone sounds and works really good, Although it chews more battery life then regular use. (3) It is a simple, easy to use phone but it also comes with some great features too. For example the speech recognition software is pretty handy when your arms are busy. (Pun intended. ; )) As well, the T9Word software helps with text messaging by not having to hit the same key over and over to get the right letter by matching the number string sequence to most common words combinations that can be made with those numbers it just predicts what word you need and gives you a list to select with a soft key if there are multiple possibilities. T9Word software helps for text messages but it isn't as fast as the predictive typing on QWERTY phone keyboard or touch screens... but for the amount of buttons it really helps bridge the gap for the need to text. (4) The clam shell advantages "Practical" and "Stylish": The Small size and light weight design of this clam flip phone is allot easier to carry around, and harder to scratch up the main display because it is protected on the inside. As far as style, the elegant flip out design seems to grab more attention when I fiddle around with it for messages, voice mail and contact selection for calls since more blocky designs tend to seem more popular options these days. (5) So if you are like me and have a mobile netbook, ipad or laptop, then maybe a bulky phone isn't necessary, and what you really need is a small portable phone that sounds good and can provide some good decent talk time. Things to improve: 1- speech recognition for making text messages would be nice. 2- longer battery life is always nice. All in all, I'd say it's a well rounded and practical phone that is great for talking! I like it and am happy with my purchase even with text messages. =) Less

The Samsung R312 offered by Public Mobile is by far the best phone they've got, all others require "daily" battery recharge and they're cheaply built, their sound quality is well below average. My Samsung R312 can last for 3 days without having to recharge the battery, that is a big plus as well as sound quality is quite good! The bad is that it doesn't have a speakerphone... Other than that, Public Mobile is just bad so I think I'll switch for Solo Mobile (new 35$ unlimited plan like public mobile but their network is excellent and they offer the new Samsung Entro that is very good). Public mobile network reception is far below average, in most cases I'll be getting about 1/5 or 2/5 signal bars. I cannot have a normal conversation with such low signals. Minimum would be 3/5, I mainly get that if I'm outside. So if you really want to go with Public Mobile forget all other phones and get this one or you'll regret it. But overall, stay away from Public Mobile and go for Solo Mobile, 35$/month unlimited incoming/outgoing, 50 texts, call display and a better choice of phones. 45$/month, unlimited texting and voicemail as well. Canada-Wide. If you go with Solo Mobile get the Samsung Entro without any doubt. Less

I picked this phone up from Public Mobile as well, and I find it simple and easy to use and very small compared to my old LG Rumor2 with Virgin Mobile. So maybe, I'm just staying in good receptive areas due to my lifestyle? Or maybe there have been upgrades in these past 5 months. Either way, regardless of the Carrier I agree that it is a good, simple, flip phone and I highly recommend it if you are more of a talker than a text messenger. PRO: (1) People have told me how good I sound on it which is nice, I suspect this might be due to the design length and arc of the R312 flip phone spanning the distance from ear to mouth compared to shorter and straighter phones that don't make it as close to the mouth. (2) It is a simple, easy to use phone but it also comes with some great features too. The speech recognition software is pretty handy when your arms are busy. (Pun intended. ; )) As well, the T9Word software helps with text messaging by not having to hit the same key over and over to get the right letter by matching the number string sequence to most common words combinations that can be made with those numbers it just predicts what word you need and gives you a list to select with a soft key if there are multiple possibilities. CON: The only negative thing I REALLY need to add is that for text messages the T9Word software helps but it isn't as fast as the predictive typing on my old QWERTY phone keyboard. Besides that obvious design feature... I would also like to note that (1) the Speaker Phone really chews up the batteries if you talk long, much more so then a regular conversation, so blue tooth might be nicer for hands free but i have yet to try it. (2) the camera is only 0.3 mega-pixels for this phone so it really isn't useful for taking really "nice" pictures.
