国内的手机带到这边可以用，但需要换SIM卡 除非富到天天用移动联通的全球通....
新加坡主要有三家电信公司 Mobile One(M1) Starhub(星展） Singtel（新电信）
网站各为
M1 www.m1.com.sg
Starhub http://www.starhub.com/
Singtel www.singtel.com
首先介绍prepaid（也就是预付费卡，充值卡的资费）
资费目前如下
singtel
Local calls
8 cents/min weekdays (Monday to Friday) 8pm to 7.59am and weekends anytime.
16 cents/min weekdays (Monday to Friday) 8am to 7.59pm.
All calls answered/ made on both lines will be charged at prevailing local talktime charges.（双向收费就是。。）
Talktime charges apply to redirected calls.
^ Free incoming calls applicable with a minimal daily deduction of $0.60 upon activation.（如果每天愿意扣6毛钱的话费，则可以办理免费接听业务. PS:在使用后面所说的128的卡，这6毛钱是扣在国际话费上的。任何预付费卡的业务都是扣在国际话费部分。
Local sms at 5 cents/SMS

就是说往这些国家打电话前加019及国家区号和本地区号（去0）会比较便宜 比如说打中国北京的座机电话号码为010-87654321 则应该拨打019861087654321 国内手机019然后加国家区号加手机号，如手机号为13901234567的，就应该拨打 019863901234567
Free Caller-ID, Call Hold, Call Waiting and Call Transfer Service （免费来电显示 第二个怎么翻译……就是第二个人打进来你可以先把第一个人的搁置 先跟第二个人说话）

这里是不同充值卡的资费 http://info.singtel.com/personal/communication/mobile/prepaid-plans/plans-top-up
其中包括一些充20块钱就是20块钱话费的卡，不多介绍。
这里额外介绍 super hot 128（也就是28块钱充值100块钱本地话费以及28块钱国际话费）Singtel这方面的网站为http://info.singtel.com/personal/communication/mobile/prepaid-plans/plans-top-up/super-hot-128-card
起自费标准为
$28 worth of IDD calls and global SMSes （28块钱国际）
$100 worth of local calls and local SMSes （100块钱本地）
FREE IDD calls to Bangladesh, China, India, Malaysia, Thailand and more
Local calls at 8 cents/min^ EVERYDAY (这个是骗人的，在官网上下面有一层小字写着真实话费，和上面所写的话费一样）
Local SMS at 5 cents/SMS （5分钱一条本地短信）
Global SMS at 15 cents/SMS（15分一条国际短信）
Value valid for 50 days（这部分话费的有效期，为50天，如果到了50天，不另外充值，那么所有账户的话费清零。如果充值，则有效期重新更正为50天，并且保留原先的余额。PS：注意，是变为50天，而不是延长，所以不要一下充好几张卡。）
Best network coverage
Free Incoming Calls*
Extend your Prepaid Mobile Card validty for another 180 days and enjoy 50 days value validity from the date of top up(180天指的是手机卡的有效期，而不是这128话费的有效期，这部分任为50天。）
Starhub
Local Calls
(Including video calls):1st min 22￠, 8￠ per min thereafter[Promotion has been extended till further notice. (Usual price: $0.18 per minute from 2nd minute thereafter).]
这里来说，starhub的话费是最贵的，特别是对于通话时间通常比较短的同学来说。
International Calls(Including Video calls~)
Local Prepaid call charges plus prevailing IDD charges (StarHub IDD 008/018)
由于拨打中国的IDD点话额外资费是免费的，所以国际电话价格和本地一样。
Local SMS (send)
5￠/SMS sent
Global SMS (send)
15￠/SMS sent
Directory Enquiry
Calls to Service 100 charged at 70￠ per call, plus local Prepaid call charges
Local GPRS(强烈建议不要开通，实在是太贵）
0.5￠/KB^ (usual: 1￠/KB)
Local & Global MMS（流量费额外自己承担）
30￠ per MMS (less than 30kb)/80￠ per MMS (30kb and more*)
Starhub的充值卡和Singtel整体模式基本一样。
除了资费标准按照Starhub的资费来，其日期同样为50天。
最后一家
M1
sm2和sm3在来到新加坡的第二天，在MOE开会的时候，就会接触到m1
会有m1公司的人在MOE那里给我们办理m1的业务。
这也是绝大多数学生都用着m1公司的业务的原因。
