MTSMC-H4-U: WCDMA 2100 not in the list, PH-NET PIN instead of READY

[Valliappan M]

Hi,

I have problem connecting MTSMC-H4-U modem to 3G network. So, i tried some of the AT commands from http://www.multitech.net/developer/wp-content/uploads/2010/10/S000483A.pdf.

I suspect two things, one is the 3g frequency used by the modem and other is the AT+CPIN? returns PH-NET PIN instead of READY (which i got in MTSMC-G2)

Below is the result for the AT commands i tried using microcom:

microcom /dev/ttyUSB3

I want to change the frequency to WCDMA 2100 as per the AT command manual and would like to know why i am receiving this PH-NET PIN instead of READY for AT+CPIN?

Any help would be much appreciated.

PS: I previously managed to make the same SIM card work with MTSMC-G2 modem by using dual band 900/1800MHz.One of the sources i refer for frequency is here:

Hi Moderators & Admins,

Could you please confirm whether my question is under the right forum? Is there any other support options(email) available from Multitech? Because i am currently evaluating whether the MTSMC-H4-U modem supports the frequency band that we expect.

From the AT command manual it says

<bandsetInd> (Band index value—When configured for ‘all regions’, all of the bands

supported by the modem will appear):

00 = All bands

01 = WCDMA 2100

02 = WCDMA 850/1900

03 = GSM 900/1800

04 = GSM 850/1900

05 = GSM ALL

06 = WCDMA 2100 GSM 900/1800

07 = WCDMA 850/1900 GSM 850/1900

08 = WCDMA ALL

09 = WCDMA 850/2100

0A = WCDMA 800/2100

0B = WCDMA 850/2100 GSM 900/1800

0C = WCDMA 850 GSM 900/1800

0D = WCDMA 850

0E = WCDMA 900

0F = WCDMA 900/2100

But in the device i get limited bands as below:

at!band=?

Index, Name

00, All bands

01, N/A (Defaults to ALL)

02, WCDMA 850/1900

03, N/A (Defaults to ALL)

04, GSM 850/1900

05, GSM ALL

06, N/A (Defaults to ALL)

07, N/A (Defaults to ALL)

08, WCDMA ALL

09, N/A (Defaults to ALL)

0A, N/A (Defaults to ALL)

0B, N/A (Defaults to ALL)

0C, N/A (Defaults to ALL)

0D, N/A (Defaults to ALL)

0E, N/A (Defaults to ALL)

0F, N/A (Defaults to ALL)

10, N/A (Defaults to ALL)

11, N/A (Defaults to ALL)



OK

Is there any way i can make the modem to use the WCDMA 2100 band?

Any help would be much appreciated.

Check the complete part number on the serial number label. The -H4 series devices will have either a -P1 or -P2 suffix in the part number. The -P2 models are locked to AT&T and will return the +CPIN: PH-NET PIN response if an AT&T SIM is not inserted. If you are using a carrier other than AT&T you need to order a -P1 model.

Hi,

Thank you for the reply.

The complete part number is MTCDP-H4-GP-P2-DK-1.0. Since it has P2, it will work only with At&T carrier? Is there any other way I can make this to work with other carriers?or I have to order a P1 model?

Also, can i atleast make it work in 2G(GPRS) mode?

[Darrik Spaude]

The P2 model is for AT&T networks. The P1 model is generic for any network including AT&T. However, if you deploy the unlocked model (P1) in the USA for use on AT&T’s network, then if there are network issues you may not get help from AT&T in resolving the problem. They approved the P2 model and expect AT&T customers to use that model.
