You will definitely get a surprise.
Whether you like the surprise or not.
TM might offer you an upgrade to Unifi10 with a new subscription fee (it won't be free).
If you think that you want a faster speed, then subscribe to Advance30 before 28 February 2017.
You will be upgraded to Advance50 after April 2017.
But you will be locked with a 2 year contract.
Remember Advance packages do not come with free calls to TM numbers.
You still have more than a month to think about it.

We all got conned by TM already.
Now unifi advanced (30m & 50M) has no free local calls to fixed line already.
Thats how they earn back the money used as 'promotions'!!! 

I took the offer for 10-30 upgrade for rm10 as well late december, now january bill shows i need to pay local fixed line calls and recent check no free upgrade but only webe or hypptv packs only
