T-Mobile Extended Range LTE 700 MHz Band 12 Cell Phone Signal Boosters

One of the selling points of extended range LTE-700 MHz also known as 700 MHz Band 12 LTE is that the cellular reception reaches twice as far. The low signal is also said to penetrate thick walls allowing four times increased coverage inside manmade constructions. The low band spectrum service is perfect for covering vast geographical regions while penetrating walls and buildings. In contrast, high band spectrum might not cover large geographical sections like extended range LTE 700-MHz does, but relay more data rapidly.

Why 700 MHz Band 12 LTE's important.

One of the benefits of extended range LTE 700 MHz is its ability to supplement mid-band spectrums. The frequency offer extra speed and capacity as well as extended reach across far-flung rural areas and suburban regions.

700MHz Band 12 LTE easily improves penetration inside buildings. The cellular signal is twice faster and strong inside buildings in contrast with mid-band spectrum ranges. As a result, the frequency enhances in-building call and data experience.

Most of United States and Canada is rural in nature with lots of vegetation, natural features like mountains, lakes and dry expanses. With extended range LTE-700 MHz cell sites, people in these regions benefit more than anyone else. The coverage in rural areas and suburban North America is extended enabling better communication. Outside densely populated urban sectors also enjoy better and cost-effective extended spectrum.

Difference between dead zones and quality 4G LTE service.

As already mentioned, United States and Canada are very expansive in geography. In some areas, extended range LTE700 MHz is the difference between top speed LTE networks and no signal at all. For instance, modern phones compatible with B12 have another usable signal to turn to. In Denver, Nexus 6 or iPhone 6 owners might see a drop in B4 coverage but the device easily finds a reliable Band 12 signal.

In Houston, those experiencing dead spots in homes in the past have reported accessing band 12 across all previous dead spots. As 700 MHz B12 LTE continues to offer a quality cell signal in spotty areas, users have compared it to turning on a mass of new cell phone towers. Even so, Band 12 isn't perfect and the mileage varies widely as the extension continues. Also, you need a smart phone that supports Band 12 to enjoy the low band spectrum signal. Most new smartphones will now have capability to detect this megahertz frequency, which was not the case just a few years ago.

Carriers supporting 700 MHz Band 12 LTE in USA.

Within U.S.A., Band 12 has become a significant investment for cell carriers who have embraced it considering its ability to cover expansive areas. Carriers and their MVNOs supporting Band 12 LTE in one form or another (already built or planned to be built within their network) and in one area or another, include:

  • AT&T Wireless network companies.
  • Sprint network companies.
  • T-Mobile network companies.
  • Verizon Wireless network companies.
  • US Cellular.
  • Bluegrass Cellular.
  • C Spire.
  • Google Fi.
  • Net 10.
  • Republic Wireless.
  • Simple Mobile.
  • Ting.
  • TPO Mobile.
  • MetroPCS.

AT&T Wireless.

AT&T is the second wireless network carrier in United States and had reported support for Extended range LTE-700 MHz as early as September 2013. According to the carrier, the rollout would be followed by interoperability support and Band 12 compatible handsets. Earlier, AT&T had referred to the adoption of Band-12 as unnecessary and expensive. By March 2015, AT&T had started working with a number of carriers across U.S. to meet its promise of supporting interoperability between Band 12 and Band 17 within the 700 MHz frequency. For AT&T customers, interoperability and support gives them a chance to roam on other extended range LTE-700 MHz carriers such as U.S. Cellular and T-Mobile.


While AT&T changed its mind on the viability of Band 12, T-Mobile had its mind fixed on it and remains arguably the king of extended range LTE-700 MHz within US. In the past few years, T-Mobile has engaged in aggressive expansion campaign to spread its network across the nation. LTE bands were on top of that list and naturally, the 700 MHz Band 12 LTE.

Between February 2017 and January 2018, T-Mobile has vastly extended its LTE network across the nation. For instance, T-Mobile was reported to have acquired three critical licenses within the 700 MHz band covering entire Montana area. By April 2017, the T-Mobile deployment of the 700 MHz Band12 LTE network was concluded, covering over 269 million individuals.

In July 2017, T-Mobile applied for the acquisition of additional licenses for the Colorado Valley, TX before it was concluded on September 2017. In Marianna, FL T-Mobile was able to deploy extended range LTE-700 MHz through WBIF, which was FCC approved by August 2017. In January 2018, it was also reported that T-Mobile was in talks with US Cellular to acquire licenses for Michigan's Western Upper Peninsula and Western Kansas to reach over 500k users.

To prepare for extended range LTE-700 MHz rollout and adoption, T-Mobile started offering Android tablets, hotspot devices and all phones compatible with Band 12 in 2016. T-Mobile also released a BYOD Check App allowing users to key in (or use scanner feature) IMEI numbers of their phones to know if they are compatible with 700 MHz B-12 LTE.

Carriers supporting 700 MHz Band 12 LTE in Canada.

In Canada, a number of carriers and their subsidiaries have already adopted the extended range LTE-700 MHz frequency. These include:

  • Bell Mobility.
  • Chatr Wireless.
  • NorthernTel (Bel Aliant).
  • Public Mobile.
  • Rogers Wireless.
  • Telus Mobility.
  • Videotron Mobile.

Cell phone signal boosters compatible with Extended range LTE-700 MHz.

One of the most observable benefits of the 700 MHz Band 12 LTE frequency is ability to reach vast geographical areas in rural and suburban areas in both Canada and USA. It means that even in rural areas where there was no cell phone signal there's definitely some coverage. While it also means the signal is weak and unreliable, you can boost it using cell phone signal amplifiers for vehicles and homes, commercial complexes or offices.

These cell phone signal boosters allow you to enjoy Band 12 LTE top speeds wherever you might be on your vehicle, home or business premises.

  • This sounds like another amazing advance in signal boosters. Here’s my question. I don’t have problems with a thick wall but rather with my home’s windows. At least that’s what I think. Is there any method for testing to see if my poor cell signal is due to a wall or a window?

  • One correction, in Canada the Chatr brand only utilizes Rogers’ HSPA network, it doesn’t have the LTE band 12/700MHz access.

  • I’ve heard of Wi-Fi, but recently the term Mi-Fi has been popping up. What is the difference between WiFi and MiFi connections?

  • My Google machine comes up with some strange stuff. I am looking for a cell phone booster and inadvertently typed in “T Mobile Signal Booster” only to come up here. It’s all good because these boosters works for a variety of cell phone carriers. That’s the beauty of these boosters, you don’t have to buy one for Verizon then buy one for T Mobile if you switch. One size does fit all.

  • There were questions about the best T-Mobile phones in 2017, but I’m also considering what are the best cell phone boosters. No matter how what brand I get, I have trouble making calls without them being dropped. A cell phone booster seems to be my best option and while I’d love a T-Mobile signal booster for free, I don’t mind shelling out some cash for one that helps me get maximum speed and call power.

  • Someone asked me, “What is band 12?” and I thought they were talking about some new Netflix show. I looked into it and found it’s the 700 MHz Band 12 LTE frequency that makes for more efficient cell phone signals, particularly in suburban and rural areas. While not all cell phone carriers seemed to realize its potential, T-Mobile seems to have done so. Throw in a cell phone booster and you have a cell phone that can make clear calls without worrying about dropped calls.
