FONA808 Mini GPS Serial Monitor Message Help!!

Hello guys,

I have build a GPS tracking using a FONA808 Mini and it worked once by showing me the longitude and latitude on the serial monitor and stating the message “Fona ok”

Now bare in mind my headers on the shield were not soldered. It worked once only after it never did. So i soldered it and i keep getting the following message.

AT
<— AT
—> ATE0
<— ATE0
—> ATE0
<— OK
—> AT+CVHU=0
<— OK
→ AT
<—
—> AT
<— AT
—> AT
<— AT
—> ATE0
<— ATE0
—> ATE0
<— OK
—> AT+CVHU=0
<— OK

It doesn’t work. I used Freeboard.io to track the location and it doesnt update at all where as it did once before i moved the shield.

may i please have some help here.
