It has one glaring weakness- it only has 4gb memory. Once the OS is on and the standard apps you're not looking at much available memory. Because Google Play won't let you download content to the SD, you can only stream because there is not enough memory to handle big media files.
Overall it is snappy with good battery life. The screen is nice but has poor viewing angles. It has that funky shape the early Xperia phones had- its thicker on the ends that in the middle.
If you have a TMo sim and are looking for a dual sim to travel, this is a must buy, or if you have a T-mo and ATT sim and want only one device this is great.
The only major flaw is about the limited internal memory. Worse, one cannot use any app2sd applications to move apps to a microSD card. There is no way of doing it, and that's confirmed by Sony's technical staff. Very disappointing since the internal 2G will quickly be filled up after about 80 apps.
Update May 2014: international data roaming issue
T-mobile has a very nice international roaming service with its Simple Choice plan: free international data, usually at 2G speed. In China it may use China Unicom's 3G network. However this cellphone failed to get the data signal. Voice roaming is fine. I enabled international data roaming with T-mobile, enabled it on the phone, set up mobile network setting and APN; nothing worked. I then inserted the same T-mobile sim card into someone else's Galaxy 3; it recognized the data network right away. After long phone calls to T-mobile and Sony, I gave up.
This also happened in Puerto Rico. It's a US territory but is considered by T-mobile as an international roaming zone. Unfortunately the data did not work in PR either.
I concluded that this must be a design defect by Sony. If anyone's Xperia M C2004 works on international data roaming, please make sure to report here. Thanks.
Update February 2015: continue on date roaming issue
I finally got fed up with the issue and decided to have it solved. Sent the cellphone to Sony repair center at Laredo, Texas. After 2 weeks, they sent me a replacement without any explanation. The problem is: the brand new replacement has the same problem. It's maddening. Sony is woefully incapable of taking care of its customer's issue. I escalated the case and am waiting for their response.
There are a few new models coming out to meet my needs (dual-sim for international travel, with T-mobile and a second carrier). Xperia Z3 D6633 is one option; but I really don't have confidence on Sony at this moment.
To be updated.
Updated on 2/12/2015:
After being ignored by SONY's custom service a few times, I called again and was eventually able to talk to a supervisor. He does not recognize that it's a defective product. When I challenged him to use any SIM of their choice, in a country of their choice to show me that the international data roaming works on the product, and a short video or in-store presentation will suffice. He simply said that they don't have any international SIM card to test in USA, neither can they travel internationally to test it. At the same time he maintained that it's carrier's problem.
Realized that SONY has no interest to deal with a customer's problem with their product, I completely gave up on them and personally will never buy any SONY product. Another star is dropped.
Final solution and conclusion:
I took the pain to unlock the boot loader, then flashed a old stock ROM 15.2.A.2.5 to the phone. After the downgrading of the firmware, the international data roaming function is back and running.
SONY screwed up their system when they upgrade the firmware, but cannot acknowledge a mistake they made and chose to leave consumer high and dry. It's sad to see that a great company slid down to be so pathetic over the decades.
I use the dual SIM card feature quite a lot, and the phone is good enough to suggest the most appropriate SIM card to use for each action by the other person’s international prefix; this is not always the best thing to do, but it’s correct most of the times (I’m more likely to call/text people in one country when I’m in that country myself, otherwise I’ll just e-mail/Skype them).
The back camera is not that of a $600 phone, but it’s still good enough that you won’t regret not having a point-and-click camera with you, unless you’re indoors.
The touch screen is very responsive, and so is the phone. The default UI theme is rather attractive in its simplicity, and I haven’t changed it yet (though I modified the “accent” color).
The battery is removable and replaceable, and I’m not sure how many phones at this feature level offer such an option.
The only thing this phone lacks is 4G, which for me is not an issue as I don’t really use data.
But when I do, this phone supports 3G (HSPA) at the highest speed, and is able to do so anywhere on the US T-Mobile network as well as any European country.
The battery duration is pretty good; with my extra-light usage (wifi off, little use overall) the phone runs about 10 days on a charge, with 2 SIM cards connected to the network. On days when I use the phone more, the screen consumption drains the battery quite a bit; a average user will probably need to recharge it every 3 days or so.
The only disappointment (if minor) is that in order to use the FM radion, you have to plug in your headphones, or the radio just won’t play anything at all (by design), so unless you plug in external self-powered speakers, there’s no way to play the radio directly through the prone without using headphones or some other external device.
The phone is light, fits nicely in the palm of my small hands, and does not slip despite being quite thin. It is quite sturdy as well, although I haven't dropped it yet! Call quality is very clear. I can clearly hear what is being said by the person on the other end of the line, and that person can also hear me quite well. There does not appear to be any distortions. Dual-SIM standby works quite well too. When there is a call on one SIM, the other SIM does not accept calls. There is an option to forward calls coming to the inactive SIM to the one in use, but I could not activate that feature - looks like it is a T-Mobile issue, and I am not going to pursue it. It serves my purpose quite well. Since this is the first time I am using a dual-SIM phone, I have to get used to making the calls through the correct SIM. The phone and messaging applications are quite adequate, and every time you make or receive a call or text, it says which SIM is being used, so you are always in the know. Quite neat.
Wi-Fi is really easy to set up and the phone remembers all the settings quite well. The T-Mobile 4G network is fast enough for me where I live, and I have had no issues with it whatsoever. You can specify one SIM to be used with data, which suits me quite well. I have one line with unlimited data, and another prepaid line without any data.
There is Android 4.2.2 on board, and the phone is quite smooth and snappy. I have installed the ADW Launcher on it, which is what I have been using for a while now, and I like it.
I do not play games, so the built-in user-accessible 2GB of storage is enough for me. I have my 16GB micro-SD card installed, and the Walkman application is great for listening to music. There are some other apps by Sony and Google that I will never use, and I would have liked a way to uninstall them without rooting the phone (thereby voiding the warranty), but I guess I cannot do that. The 5MP camera with flash is also adequate for me.
The screen is quite sharp and legible both indoors and outdoors. Brightness can be automatically adjusted to light conditions. Battery life has also been pretty good - I can get a full day and a half the way I use the phone.
To sum it up, I did not have much choice when it came to reliable dual-SIM phones that support the T-Mobile 4G bands here in the USA. I had to choose between the Sony Xperia M Dual and the Huawei Ascend P6 Dual. I read all the reviews I could find and decided on the Sony handset. I must say that the phone perfectly fits my needs and I am very satisfied with it. I would recommend this phone to anyone with similar needs.
