Your recent TelCel Banda Ancha experience, please.

[DonJuane]

I made the same mistake you did multiple times, something is wrong with the forum that I'd have to spend some time duplicating to actually report the problem. I think it is after you make a post, other posts appear under your posted reply and they appear to you as new posts, yet they may be several years old. I was once challenged for why I was responding to so many old posts and this was the reason. You have to look carefully that the ones coming to the top of the post list are from a recent date.

Otherwise my 2 cents on this subject, I ordered some of these off eBay
Unlocked Huawei E397Bu-501 100 Mbps 4G LTE FDD TDD Mobile Broadband Modem

From what I can tell from a few days of research, the 501 version of the E379Bu is only for Telcel and while they are being sold in the US on eBay, this may be due to Telcel no longer carrying many of the USB style modems and perhaps they dumped their supplies to a US wholesaler. By the way I pity those in the US who are buying these thinking they will get LTE on the US carriers. They won't because Telcel's 4G is different than any US carrier.

I called all over northern Mexico (July 2017) and I couldn't find a single city's main Telcel office selling these high performance USB modems any longer, even though they are advertised as still supported on Telcel's website. Do take note here that Huawei E397 comes in many different versions, supporting different bands of different phone companies and the 501 iteration is only for Telcel Mexico. Also note that I think this is the only modem that will deliver the desired premium speed on Telcel's new 4G service. Still you could argue that speed does you little good when the data is so expensive and with this idea, some might opt for the cheaper 3G equipment just to keep from going over their limit. I know I easily use 30 +G per month on my wired connection and I don't stream.

Now with this modem, adding something like a GL-AR150 mini router loaded with firmware from ofmodemsandmen.com , a multi-band yagi antenna like the weBoost 700-2700 MHz Wide Band Directional Antenna along with the proper TS9 to N pigtail, this setup could be put in a waterproof container and mounted outside any house in a line of sight with the Telcel towers and a near 100% signal could likely be enjoyed for the Telcel service. So performance can be addressed with the proper equipment, while not the data cost.

Outside the city, however Telcel while traditionally the carrier with the widest coverage is not always available with data. I have seen many occurrences while traveling cross-country where a 5 bar will be seen on voice and the infamous E or Edge data will appear with sometimes a 1-2G data rate, less than dial up.

But cross country coverage was not the topic of this post.
