@io Hi I ordered IoT Easy Connect Start with the understanding this can be used for experimenting with the T-Mobile NB-IoT network. I have no problem with ordering new SIM cards but are these with a price or are they like the Easy Connect Start SIM’s, as in are they free?

@fm I have looked at the connection to T-Mobile Netherlands and it does seem to find it.

09:06:42.148 -> AT+COPS=?
09:06:54.566 -> +COPS: (1,“T-Mobile NL”,“TMO N”,“20416”,9),(0-4),(0-2)

But as soon if I try to make the connetion it fails.

09:09:31.084 -> AT+COPS=1,2,“20416”
*MRPM: PDN CONNECT BLOCK,2,310
09:09:32.174 ->
09:09:32.174 -> +CREG: 0
09:09:32.174 ->
09:09:32.174 -> +CME ERROR: no network service

Hi I’m using the SIM7020E from Waveshare (https://www.waveshare.com/wiki/SIM7020E_NB-IoT_HAT#SIM7020_Datasheets) in comabination with the IoT Easy Connect Start. I have been using the following AT commands to get a connection with IoT Creators:

12:35:44.962 -> AT+CFUN=0
12:35:45.380 -> +CPIN: NOT READY
12:35:45.525 ->
12:35:45.525 -> OK
12:35:51.435 -> AT+CREG=2
12:35:51.528 -> OK
12:35:58.200 -> AT*MCGDEFCONT=“IP”,“cdp.iot.t-mobile.nl”
12:35:58.530 -> OK
12:36:05.358 -> AT+CFUN=1
12:36:05.733 -> OK
12:36:05.874 ->
12:36:05.921 -> +CPIN: READY
12:36:06.012 ->
12:36:06.060 -> +CREG: 2
12:36:15.751 -> AT+CBAND=8
12:36:15.891 ->
12:36:15.891 -> OK
12:36:23.979 -> AT+COPS=1,2,“20416”
*MRPM: PDN CONNECT BLOCK,2,770 <–No idea what this means, the last number is in
seconds counting from 900 (15 min)
12:37:03.468 ->
12:37:03.468 -> +CREG: 3
12:37:03.560 ->
12:37:03.560 -> ERROR

While looking for the problem I used AT+CMEE=2 to see the error message and got the following:

13:16:18.184 -> at+cops=1,2,“20416”

13:16:18.369 -> +CREG: 2
13:16:19.260 -> *MRPM: PDN CONNECT BLOCK,2,210
13:16:19.495 ->
13:16:19.542 -> +CREG: 0
13:16:19.590 ->
13:16:19.638 -> +CME ERROR: no network service

13:19:42.645 -> at+cpol=?
13:19:42.741 -> +CME ERROR: SIM File not present

Thinking the last error must mean the problem lies with the SIM cards, I put a 4G SIM I had in the SIM7020E wich didn’t gave that error message.

Does someone know the problem or did someone get the same errors as I and found the solution?
