Do you want to call or text your friends and loved ones as much as you want, but you are on a tight budget? Thanks to Smart unli call and text promos (Smart UCT promos), you can talk and chat with anyone in the Philippines, for as long and as much as you want, without worrying about the costs of long-distance communication.
Before unlimited call and text promos were introduced in the early 2000s, cellphone calls incurred a per-minute charge. You wouldn’t get charged if a call lasts for only a few seconds, so “dropped calls” became popular among subscribers who wanted to save on prepaid load. Telecom companies soon discovered the loophole and started charging even if the call lasts for 5 seconds or less. That was until Sun Cellular introduced the concept of unlimited calls and texts, which was later adopted by other telcos.
Unli call and text promos quickly caught on with the masses, fueling a competition between rival telecom companies on who can offer the most attractive promos. The fierce competition continues to rage on today and the result is that you can register to Smart unlimited call and text promos for as low as ₱10 per day. Most prepaid subscribers are budget-conscious and many of them would only register to promos that offer unlimited calls or SMS, or both.
Smart UCT promos offer unlimited call minutes to Smart, TNT and Sun Cellular, as well as unlimited text messages to all networks including Globe and TM. Not only that, Smart unli call and text promos also provide mobile data for Facebook, Messenger and WhatsApp, so you can keep up with your friends and loved ones on these apps. Smart UCT promos range anywhere from ₱25 (UCT25) to ₱600 (UCT600), with validity from 1 day up to 60 days (2 months).
