Huawei B311-521 Unlocked 4G LTE 150 Mbps Mobile Wi-Fi Router (3G/4G LTE in USA, Canada, LATM, Venezuela, Caribbean, Brasil, Europe, Asia, Middle East, Africa)

Our company requires that we travel to work in Mexico, our phones and tablets are in roaming mode all the time , the signal from AT&T from the US side does not work well in Mexico. So as a test drive our manager let us buy one of these routers. I bought an SM card from Telcel ($3 USD) and bought some airtime so we can send emails, work with out work orders software, navigate thru the web and have internet access in general. This router works perfect for me , its just plug and play, boot time its around 20-25 seconds. On the back of it theres an RJ11 plug ( you might plug a regular phone landline type there?? I am willing to try it out ) and maybe make some calls from there. In Mexico ( at least in the area that we work) you will have to pay for either voice and data service or data only. There are some other services that requires contract but for the test drive im paying around $27usd and i have access for like around a month more or less with normal use. Great product.
