Hey, adding some code that should get you there and that includes a lot of useful debugging stuff. You'll need to change the apn / band .

import time
import socket
from network import LTE

# Connect to Mobile
def connect_mobile(settings):

    lte = LTE()

    connected = False

    display.set_mode("Trying: LTE")

    try:
        lte.init()
        print("LTE init success")
    except: 
        print("LTE init failed")

    print(lte.ue_coverage()) # Check network coverage (True, is yes)

    print(lte.send_at_cmd('AT!="fsm"'))

    print(lte.send_at_cmd("AT"))

    print(lte.send_at_cmd("ATI1"))

    print(lte.send_at_cmd("AT+CSMINS?"))

    print(lte.send_at_cmd("AT+CFUN?"))

    print(lte.send_at_cmd('ATI+CIMI')) # Request IMSI

    print(lte.send_at_cmd('ATI+SQNCTM=?'))


    print("Add band, will be much faster")
    #lte.attach(band=None, apn="iot.1nce.net") #band : to scan for networks. If no band (or None) is specified, all bands will be scanned. The possible values for the band are: 3, 4, 5, 8, 12, 13, 20 and 28.
    lte.attach(band=20, apn="iot.1nce.net") # works
    print("attaching..",end='')
    while not lte.isattached():
        time.sleep(0.25)

        print('.',end='')
        print(lte.send_at_cmd('AT!="fsm"'))         # get the System FSM

    print("attached!")


    # once attached
    print(lte.send_at_cmd("AT+CSQ")) # Signal quality, returns <ssid> (), <ber>
    # SSID (received signal strength indication)
    ## 0: -113dBm or less
    ## 1: -111 dBm
    ## 2..30: -109..-53 dBm
    ## 31: -51 dBm or greater (best)
    ## 99: not known or not detectable

    # ber : channel bit error rate in percent
    ## 0..7: see table
    ## 9: not known or not detectable


    lte.connect()

    print("connecting [##",end='')
    while not lte.isconnected():
        time.sleep(0.25)
        print('#',end='')

        print(lte.send_at_cmd('AT!="fsm"'))
    print("] connected!")

    print(socket.getaddrinfo('pybytes.pycom.io', 80))  

    lte.deinit() # Disables LTE modem completely

    return connected
