Fuck you, Globe Telecom

I get these spam Globe Svcs+ messages every 5 minutes. I think they started a only a few days ago. They don't show up on my inbox but they pop up on my phone's screen uninvited and very intrusive. They disappear after about 2 minutes on their own but that's 2 minutes too long. If I get my hands on the person responsible for this I wish him the hell of eternal waking. (Sandman Vol 1 I think.)

There's another one! Fuck you GLOBE!

EDIT: I am switching to Smart.
EDIT: Thank you, Ralph. I'll try what you said.
