How to set the mobile phone to send SMS successfully without deducting money?

Setting with mobile phone, the method is: SMS-SMS setting-SIM card information setting-mode setting-mode 1.2.3.4, choose any one, mode name/blank. Sms center number /+4477850 12998 (mobile)+120859789 15 (Unicom). SMS is valid for six hours. Send format/text. After that, it's ok. texting is free. Most games are free to play and download, so don't order them if they are launched by regular companies. Some games need to be charged, because that kind of game can be sent successfully without the SMS center number. Deduct if you have money. I hope I can help you.
