Your Booster Stopped Working - What do you do?

The 5G Technology Transition

In 2021, an average Canadian cellular rate plan was approximately 5GB per month. Today, the average rate plan is around 150GB per month. This additional network capacity primarily comes from additional spectrums. Specifically, the network is ‘forcing’ greater use of existing and new mid-band frequencies.

If the phone connects to a new frequency NOT amplified by the 5-band booster (7/66/71)… it will seem as if the booster is not working.

​To test why your booster may have stopped working, please do the following:

  1. Are the new Frequencies (7/66/71) Broadcast near your building? Contact us at and we can take a look for you.

  2. Is your phone “Hung” on one of the new frequencies inside of the building? To find out go to your dialpad and key in the following based on your brand. Apple *3001#12345#* / Samsung *#0011#

  3. When you do a power cycle (turn airplane mode on/off) does the phone then connect to new and un-amplified frequency?   

  4. If after the power cycle, the phone still connects to a new but weak frequency… the building is leaky… Upgrade to SureCall Fusion Professional 2.0 8-band booster.

Lower bands are precious. The signal travels further,  bends around obstructions and generally penetrates walls better. 600 MHz is the lowest low-band frequency. The best for rural under-served customers / Rural 5G
If you’re a business, talk about how you started and share your professional journey.

Higher bands have more frequency (throughput) capacity. Faster wireless data means more spectrum is required and that means even higher frequencies will be required in the future. The two new Higher bands 66 & 7 have lots of spectrum and will have reconnect priority.

Meet the 'NEW' Frequencies

Band-7  140 MHz (2500-2570 Up / 2620-2690 Down)

This started as an educational spectrum. Some know the spectrum as Inukshuk. Band-7 is the largest FDD frequency in Canada. One carrier has 40 MHz wide Band-7 channels! When Band-7 is available, it is almost always the carrier reconnect priority. There are many towers with 80 MHz of Band-7 per sector! We know of MANY instances where SureCall/Wilson/Nextivity/Uniden/SmoothTalker building boosters stopped “apparently” boosting because the phones were connected on Band-7.  Band-7 is currently broadcast from 13,817 towers

Band-71  70 MHz  (663–698 Up / 617–652 Down)

This was a TV spectrum (UHF Channels 38-51) that was re-purposed for Cellular Communications. The Auction in Canada was in Feb 2019. Telus and Rogers were the big buyers, and both plan to use 600MHz for Rural 5G Services. This is now the lowest cellular frequency. It will travel further and should bend better to serve edge-of-network Canadians. The roll-out of Band-71 has been much slower than expected on the Telus side. In total, there are 5,679 towers in Canada but we expect 600MHz will be an important frequency for Rural Canadians by late 2024 – therefore Band-71 is an important frequency for SureCall. Even if you are installing 5-band boosters, ensure the pass-band for your DAS components is at least 617-2700 MHz.

AWS-3 / Band-66  50 MHz (1755-1780 Up / 2155-2180 Down)

This spectrum is contiguous to AWS-1 (Band-4). This frequency was prioritized because it is preferred Urban 5G

for some of the Carriers.  We want to avoid 5G phones connected on unamplified frequencies in the future.  

AWS-3 is currently broadcast from 8,467 towers.
