I’ve just bought two WF723CA home phone hubs to upgrade from WF721s. Taking my Dad’s sim card from the old hub and putting it into the new one is leaving me with red blinking lights which, according to the user manual, means SIM card issues. The old sim card was a nano housed in extra plastic to fit the 721. Do I have to go buy a new SIM card and register it through self serve on my Dad’s Koodo account for his phone number and phone service to work properly?

How to make an old SIM card work using WF723CA home phone hub?

Hi
- I was just coming back online to post here; thank you for addressing my issue!
I:
- Walked to the Koodo booth at Saint Laurent mall nearby
- Bought two new 5G sim cards
- At home, swapped the sims on both mine and my father’s Koodo accounts
- After waiting around 20 minutes, installed the new cards and waited out those red lights, which turned green after the devices started up plus a short period of time afterwards
- Successfully made a phone call to someone outside our home
- Successfully made phone calls from my phone to my dad’s and vice-versa
Thank you Oliver for your efforts, they’re appreciated. All is well with 3G left behind and current phone service intact.
Hi there,
If the sim card is as you describe, have you pushed on the nano sim portion of the sim card and removed the micro sim outer layer? You should be able to push it out and remove the micro sim card outer layer that is around it. A diagram of each of the portions of the sim card can be found here: SIM card 101 | Koodo Mobile
Once you do this, the sim card will remain in its nano sim compatible state. This will then be usable with the WF723CA and you will not require a replacement sim card. If you inserted the nano sim with the micro plastic adapter around it, the new device may have issues lining up the sim card pins causing connection issues as it is only nano sim compatible.
Hey Oliver,
I had removed that micro sim portion already and have just attempted to reseat the nano sim twice. Unfortunately, I’m still having the same problem. I wonder if there’s some registration issue with the hub swap. Maybe there’s supposed to be some reset or other change since I’m upgrading hardware / network service?
hmm interesting. For the Koodo side of things, there is nothing that should need to be done. The sim card contains the plan and phone number, but the model registered that is being used on the network changes once a call is made. This is free to be changed as long as the device is compatible with the Koodo network so nothing further should be required there.
To confirm, when you insert the sim card into the device, is it in the correct orientation as found here so that the sim cards golden pins are facing that of the device when it is inserted and that it is facing the correct direction? It is important it is inserted correctly in the slot and that the pins are undamaged. In addition, do you find the same error persists with the second device? That way we can narrow it down if it is only one with the problem or both.
Yes, the orientation and facing are correct. I don’t think the sim cards are damaged as they were working fine until some minutes ago.
Trying the second device now, it’s the same issue all over again, and with a busy signal on the receiver just like Dad’s setup. Problem is, now I have no working phone :/
