✔ 最佳答案
It should be safe if and only if:
1) you really connected to PCCW hot-spot rather than other access points near you with stronger radio signal strength. SSID is not so realiable at all.
2) MUST enable security protocol (e.g. WEP, WAP, etc) to ensure the data transmission between your mobile device and PCCW access point.
3) check there is a key icon at lower status bar while the information of security Certificate is valid for that bank. (to ensure that your mobile device is actuallly connected to bank's server)
4) Encryption of transmiitted end-to-end data is a must by default.
Otherwise, DO NOT use the wireless connection for stock trading (or other important) transactions.
