+CREG: 1,“4E3C”,“5797”  
+CREG: 0  
+CREG: 2  
+CREG: 1,“4E3C”,“5797”  
+CREG: 0  
+CREG: 2  
+CREG: 1,“4E3C”,“5797”  
+CREG: 0

first I thought to check antenna and signal quality:  
OK  
at+csq  
+CSQ: 0,99  
OK  
at+csq  
+CSQ: 0,99  
OK  
at+csq  
+CSQ: 21,99  
OK  
at+csq  
+CSQ: 0,99

and checking cind ( second bit should be signal quality )  
OK  
at +cind?  
+CIND: 0,0,0,0,0,0,0  
OK  
at +cind?  
+CIND: 0,4,0,0,0,0,0  
OK  
at +cind?  
+CIND: 0,4,0,0,0,0,0  
OK  
at +cind?  
+CIND: 0,0,0,0,0,0,0

i also check cell information( six value should be rxsignal level)  
AT \*PSENGI=0  
\*PSSCI: 0,7,-5843,4100,45,0,0,0,0,0,0,0,0,0,9,0,0,0,80
