In October 2018 I purchased a SIM card from this company. And use 6 months, then I upgrade to SIM for g and I use the sim for 3 months more. At at that time I had no problem using the sim. But shortly thereafter, the company's network service experience many problems. I noticed a lot of calls where drop it on these companies Network and internet speed was very slow. Then I call this companies customer care and let me tell them the problem, but they did not solve any of my problems. Just tell me know that something the problem will be solved. Then a month later the problem is not resolved full stop then I called customer care again at this company, but this time 1 from customer care treated me very badly. since then I have not used the SIM card of this company.
