Lebara lies about roaming

I buy lebara because they show in India 30 GB we can use but I still not finished my limit but they stopped my data

India is one of the Roam Like Home destinations Gurmukhbrar1 so you can use you phone as normal. The 30GB is the upper limit, if your plan is lower, 10GB for example then that would be the upper limit for data. More information here.
