❓ Help New Globe Prepaid Sim but no Signal

[blxnk]

Hi po mga bossing. Kaka-sim replacement lang po nitong globe prepaid sim ko kahapon then sabi ng Globe antayin ko daw 24hrs bago ko isalpak...then kanina naisalpak ko na sya, nagkasignal naman sya nung mga first 20seconds tas biglang may nagtext tas after nun nawala ulit signal. Until now wala padin.
Naiport ko yung number ko from TM to Globe Prepaid last October 2. Nawalan ng signal kaya pinasim replacement ko.
Any ideas po? Salamat
