It appears to be an in-browser JavaScript error.

Uncaught SyntaxError: Unexpected token ':'

Seems related to the SIM card capacity logic. sms_tool is doing fine:

# sms_tool -d /dev/ttyUSB2 status
Storage type: SM, used: 5, total: 5

XHR request to readsim also works fine, regardless of whether I configure SIM card or memory storage area - but only when done independently of the UI:

% curl 'http://XXX/cgi-bin/luci/admin/modem/sms/readsim?XXX' \
  -H 'Connection: keep-alive' \
  -H 'User-Agent: XXX' \
  -H 'DNT: 1' \
  -H 'Accept: */*' \
  -H 'Referer: http://XXX/cgi-bin/luci/admin/modem/sms/readsms' \
  -H 'Accept-Language: en-US,en;q=0.9,pl;q=0.8' \
  -H 'Cookie: sysauth=XXX' \
  --compressed \
  --insecure
{"all":"255","use":"0"}

% curl 'http://192.168.10.1/cgi-bin/luci/admin/modem/sms/readsim?XXX' \
  -H 'Connection: keep-alive' \
  -H 'User-Agent: XXX' \
  -H 'DNT: 1' \
  -H 'Accept: */*' \
  -H 'Referer: http://XXX/cgi-bin/luci/admin/modem/sms/readsms' \
  -H 'Accept-Language: en-US,en;q=0.9,pl;q=0.8' \
  -H 'Cookie: sysauth=XXX' \
  --compressed \
  --insecure
{"all":"5","use":"5"}

It's worth noting that when memory storage is set up, the UI doesn't throw any in-browser exceptions, and the capacity is correctly shown as 0/255.

Okay, found the bug:

    local statusb = luci.util.exec("sms_tool -s" .. smsmem .. " -d ".. devv .. " status")
    local all = string.sub (statusb, -4)

The code assumes the number has 3 digits. Well. Mine has one. Smarter parsing of sms_tool status is needed.

Fix:

        local all = statusb:match('[^: ]+$')
