      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,-55,0,54-54
      
      
      

      Whatever 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.

          I have done exactly in the comments and here are the results:

          AT+CGPADDR
          +CGPADDR: 1,0.0.0.0,0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0
          +CGPADDR: 13,0.0.0.0
          
           --> AT+CPSI?
          +CPSI: GSM,Online,286-01,0x8e36,34500,61 EGSM 900,-55,0,54-541
