When roaming in El Salvador, I am able to view 8 options, 4 of which are 3G. Only one 3G network will connect automatically or manually which is Digicel. On that network across many parts of San Salvador where the coverage map is solid, I get speed tests of 0.10-0.25 Mbps.
On reddit, there is a similar post from 2014. Responses focus on the device used. I am using the oneplus 2. This is a dual SIM phone and my other SIM is a local SIM with Claro. On that SIM I get between 1.5-5.0 Mbps using the Claro 3g network. Ironically, the Claro 3g network does show with the t-mobile SIM but sometimes (not always) shows forbidden like in this image.
Any thoughts on how I can connect to a better network?
