Can not force SIMCOMM 7000E to connect to LTE over GSM
-
Hey everyone. I live in Turkey and bought Botletics SIMCOMM 7000E shield along with Hologram Global SIMCARD. For over a week, I am trying to connect to the LTE network but everytime it connects to GSM network.
Prerequisite Knowledge:
NB-IoT Coverage:
Turkcell: B20 Vodafone: B8 bands according to the lin(https://halberdbastion.com/intelligence/geographic-regions/europe/turkey)Hologram Support In Turkey:
Turkcell, Vodafone, Turk Telekom
https://hologram.io/pricing/coverage/Below is the configuration I use;
// LTE Only --> AT+CNMP? +CNMP: 38 // Both NB*IoT and LTE-M, to be safe --> AT+CMNB? +CMNB: 3 // 28602: Vodafone and 28603: Turk Telekom --> AT+COPS=? +COPS: (0,"TURKCELL","TURKCELL","28601",0),(0,"286 02","286 02","28602",0),(0,"286 03","286 03","28603",0),,(0,1,2,3,4),(0,1,2) // Network settings --> AT+CGDCONT? +CGDCONT: 1,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0 +CGDCONT: 13,"IP","hologram","0.0.0.0",0,0,0,0 // Band settings, default --> AT+CBANDCFG? +CBANDCFG: "CAT-M",3,8,20,28 +CBANDCFG: "NB-IOT",3,8,20,28 // Automatic connection --> AT+COPS? +COPS: 0 // Roaming --> AT+CREG? +CREG: 0,5 // Signal strength seems good --> AT+CSQ +CSQ: 29,99 // Connected network: Turkcell GSM --> AT+CPSI? +CPSI: GSM,Online,286-01,0x8e36,34500,61 EGSM 900,-55,0,54-54Whatever I do, connection is always the GSM one instead of LTE. Do I miss a certain important AT command? Or maybe, there might be problem with Hologram or SIMCOMM7000E, or even with carriers.
Thanks in advance.
