I have two phones, one a cheap, nasty little Nokia, the other, a Samsung S5; both use Telkonsel SIM cards.
I use Telkomsel because the coverage is good, seemingly regardless of where I am, but they spam the merry crap out of me.
The small Nokia only gets the advertising stuff, but I can block that directly from the phone, so no problems.
The smartphone gets three lots of Telkomsel toilet fodder:
Lots of SMS regardling total crap special offers I have absolutely no interest in, all from a couple of numbers that are SIM card numbers, so won't block.
Loads of SMS from the top up "check data" number - I can't block this because the useful notifications came from there. Most of this is telling me I'm not using the data at night - I won't because I turn the phone off.
These first two are so common, I keep having to silent my phone as they disturb various meetings and other stuff.
Telkomsel divert my web searches to one of their pathetic, no, moronic advertising sites.
I've allowed the data to run out and fully intend to go to Telkom's office when I can with the intention of telling them to stop their stupid spam, or waive bye bye.
Question is, if I do that, can anyone suggest another supplier that doesn't send all the crap?
(I'm really miffed at Telkomsel)
