Portawifi is Huawei E355....  I use it before... WHY?

WOW...  you have stock to sell in WTS thread.

reason to sell : reseller

and you're reseller... to be honest, why not test yourself, at least you know your item well as seller. Be like a few seller here (in this thread), they really know it and can answer most of questions fast and accurate.

I have 2 units before... because I find it really easy to use, quite stable too. Both sold my own brother and his fren to use when work abroad. Never had any complaints from him and his fren. They even ask me to look for more units but that time no stock.

My wife also love it, she just need to plug to any usb, wait for awhile and use.

Just my 2 cents.

There are tons of good review on my thread
