T-Mobile 5G: An Experiment with Fixed Wireless Internet Access

t-mobile-gateway-v4-frontIn the next few weeks we’ll crest the first anniversary of Hurricane Beryl, which had quite an impact hereabouts. In the storm we lost power for a less than two days. However, our Comcast/Xfinity internet access was out for a week. As someone who works full-time from a home office, that was a problem for me. As a contract IT worker, no internet access means no money. No buénno.

My laptop, a Lenovo X1 Carbon Gen7 from 2019, has the optional 4G mobile data access module. It’s part of our Mint Mobile family plan. So, at some level I can be online with just the laptop. That provides a minimal level of productivity.

Similarly, I can tether my desktop and perhaps one or two small devices to my mobile phone. That’s ok for an afternoon, but not a good solution for a week or more.

The 4G speed test on the laptop screen reflects 4G LTE access, not 5G. Also, Mint Mobile data rates are often lower than T-Mobile’s own clients. Even though T-Mobile now owns Mint, the MVNO customers are given lower priority on the network.

Then it occurred to me that all the mobile carriers had been promoting fixed wireless service in the neighborhood. In post-Beryl Houston, power was out at our home, but not too far away there was a T-Mobile store that was open for business as usual. They had a 5G fixed wireless devices for $0 with $60/month and no contract term. It seemed like potentially a good solution. At least, there was little to risk in trying it on for size.

T-Mobile: Breaking-up is very hard to do!

We have used T-Mobile for our mobile phones since 2005. Over the course of 2021 I grew frustrated With T-Mobile. They had become too costly. There were no deals for existing customers. As our monthly mobile bill approached $200 I felt there must be a better way.

In December I decided to make a change. In truth, I’d made this determination in the early summer, but had to wait until the end of the 24 month promo deal associated with our current pair of Pixel 4 phones. That agreement ended on December 13th.

December 18, 2022

Free of the encumbrance of the purchase arrangement, I ported our two active numbers to Mint Mobile on December 18th.

Mint vs TMobile

Mint Mobile is a MVNO that offers well-priced prepaid service on T-Mobile’s network. So, I was confident that the experience of the service would be unchanged. We’d just cut our monthly cost.

I took advantage of a holiday promo, paying $240 for 6 months of 3 lines, where each line had unlimited voice & text, with 15 GB of data. 15GB is more than we actually need, but the price was good and I didn’t want to feel constrained.

The third SIM was for my Lenovo X1 Carbon laptop, which has a built-in LTE radio. For the past couple of years the laptop serves as a backup to our Comcast Business Class service. Mint doesn’t actually offer data-only (aka tablet) SIMs. I just got an extra voice line and put the SIM in my laptop.

The cost of the 6 month term was very appealing given that we had been paying T-Mobile $185 every month!

In just a few days I received the SIM kits. The porting process went smoothly, taking about 30 minutes for each of our phones. The SIM card for the laptop was a new number. It just seemed to work. There were no issues at all with the transition to Mint Mobile.

Offline Today

From 3am this morning our home network has been offline. This was expected. Comcast, our primary access provider, was quite good about notifying us of a planned fiber upgrade. The process has been taking areas of the neighborhood offline briefly…

T-Mobile Moves Beyond HDVoice

T-Mobile Nexus5 EVSI’ve been a T-Mobile customer for a long time. In fact, my transition to T-Mobile happened when I bought my first smart phone, a Blackberry 8100 (aka Pearl).

More recently I’ve been using an LG-made Nexus 5. No, not the newer 5X. Late last year I semi-regressed from a One+ One to a Nexus 5. One of the reasons for that step backward in time was to finally be able to enjoy mobile HDVoice calls to my wife, who also carries a Nexus 5.

T-Mobile, who lead the US in the rollout of mobile HDVoice, supports it’s use for in-network calls between a list of supported handsets, including the Nexus 5. That initial rollout of HDVoice came before the big build of their LTE network. They enabled the AMR-WB codec (aka G.722.2) over their existing 3G HSPA+ network.

Most other US carriers waited until their LTE rollout to launch HDVoice. An LTE network is natively an IP network, readily supporting advanced voice codecs and video. When the voice calls are handled over the LTE network it’s called Voice-Over-LTE or VoLTE, which is very different from how voice was handled on 3G networks.

Q1-2016 Broadband Update: Bye Bye Global Capacity, Hello Tachus!

According to Bob Dylan, “The times they are a-changing.” I certainly hope so. I’ve made some changes to our broadband service hereabouts, and I’m hopeful about a new alternative. The details of these two things are worth sharing.

I’ve long held that someone in a technology business, who works from a home office full time, should have redundant forms of internet access. If you’re going to have redundant access they should use different modes of connection. That way a single errant truck or backhoe doesn’t take out both of your services.

This belief was strengthened by our own experience in events like Hurricane Ike in 2008. We lost Comcast service for several weeks, falling back to our stodgy old DSL circuit. The DSL meant that we had IP phones running the morning after the storm, when even cellular service was down, amazed and confounded our neighbors.

Our first broadband service to this location was a DSL circuit. The name on the bill changed numerous times. What started out as Sprint Ion devolved into Earthlink, then Covad, Megapath, and most recently Global Capacity. The data rate was slow, but reliability was high.
