如何判断泰国手机号码没有有效期了？
<a>1、ais</a>
<a>You can only receive incoming calls</a>
<a>To keep your number and avoid service termination.</a>
<a>2、truemove</a>
<a>Please top up within to avoid termination of service.</a>
<a>3、dtac</a>
<a>you have no validity days left. Only incoming calls are allowed.</a>
<a>查询余额信息时,显示以上信息就表示需要充值话费了</a>
