Try to use localmonero as much as possible. That way, you will be stimulating the local monero sellers in your area. Much better than relying on faceless corpos for your XMR hit.
If that is not possible/expensive/etc. you can always get some LTC on a centralized or decentralized exchange and use the in-wallet exchange services of stackwallet.com or cakewallet.com
LTC has cheaper transactions fees compared to BTC. That makes LTC a better onramp onto XMR.
