Need a SIM with PSM / eDRX

SilasValera

Hi Jared
I have nRF Feather and also my custom board with nRF9160. The nRF Feather came with Hologram SIM and I am trying to test the PSM / eDRX features. The Hologram SIM uses Sprint as network provider in NJ, and unfortunately Sprint does not support PSM / eDRX.
Would you please suggest a SIM where I can use the PSM / eDRX features? The power save mode is really key feature needed for our smart devices. Really appreciate your help!
Thanks

SilasValera I have some Soracom SIMs here I can send your way. They support TMobile, AT&T an Sprint I believe.

SilasValera

Wow! Appreciate your super quick response!
Sure would love to receive that and try! please let me know how can I receive, I can send you my details.
Hope TMobile / AT&T support PSM features. Anyone tested this yet?

Thanks

Also, I haven’t played with PSM/eDRX but I’ve been rounding the corner on some work where it will be necessary. I’ll update this thread with any findings.

Hi Jared,
I just sent an email to you !

Thank you so much!!

Hi Jared,
Received the SoraCom SIM cards! Thank you so much!
Also ran some tests, it uses ATT network, and the PSM does work!! I need to do more tests on setting up own PSM timer intervals, but I am sure that will work as expected.
Thank you so much for your help!

SilasValera Soracom sims work in norcal as well… i’ve been using them with PSM and LWM2M queued mode (my lwm2m server is in AWS so it even works with DTLS as soracom IP address is static and in AWS)

Hi David
thank you so much for your post! sorry I missed to reply!
And you have implemented just the one that I am looking help for!
I need to implement LWM2M with the queued mode. At present my field devices (nodes) are using LoRa protocol, and they work really nice with our own IoT platform (we use the open source ChirpStack LoRa network server which communicates with our IoT server app). We now want to implement LwM2M protocol using nrf9160 integrated in our NBIoT field devices. We have tested the nrf9160 with serial light modem and PSM. Will you please help with some guidelines?
Thanks
