Online casinos offer users the possibility of playing on the go straight from their mobile phones. The only problem is that not all of them offer very good mobile apps with which you can place real bets. This leaves you with the option of playing on your mobile browser and this will lead to other problems because not all software creators treat all devices equally.
You should at all costs avoid purchasing a Windows Phone. The main reason is that very few online casinos offer software for Windows Phones. You will find a couple of apps which offer video slot machines but it is a rather small market. So if you already own a Windows Phone my best advice is to get a new phone if you really want to explore online gaming on the go.
Blackberry is another type of mobile phone you should stay away from. They might be a good option for you as a general phone and as a business device, but for online gambling you are better off with pretty much any other option.
iPhones on the other hand are good for such a hobby. The main thing you should look for is a big screen. The smaller ones will squash the games and make it hard for you to notice all of the details. The main advantage is that 99.9% of casino games for mobile will be created for iOS devices like iPhone and iPad.
Your other ideal option is an Android phone. Just like iOS most online gambling sites will have support for this OS. Given the huge market of Android phones it is rather easy to find one that suits your needs. Once again you should go for the biggest screen you can get and also find comfortable carrying around with you.
So there you have it, if you want to buy a new mobile phone for the sole purpose of gambling on the move, iOS and Android are the ideal ones to go for.
