Unless you are only planning on making occasional phone calls on this device without holding many contacts or personalizing the ringtone, this phone is not for you, especially at this price. The lack of internal memory prevents you from saving more than a handful of games, pictures, ringtones, or text messages without causing it to lock up due to a "lack of internal memory". There are many better phones available at better prices, especially if you are a T-Mobile To Go customer. If you do use To Go, purchase a terrible phone (like this, only cheaper) for the SIM card, then upgrade to an Unlocked Phone on Amazon. You won't be nearly as frustrated (unless you try to download from T-Zones, which can be a hassle, but I would rather not have this phone and not be able to download) as I have been, wasting my money on downloads only to discover that they won't fit in, even when I have barely anything on my phone. Unless customization and having control over your phone (instead of the other way around) aren't for you, run away NOW!
