I can get the CELLv1.0 device to connect to T-Mobile US (310260) with UMTS, but I can't seem to get it to connect with HSDPA. I'm in Gilbert, Arizona, USA in an area with decent signal coverage.
Code: Select all
*CNTI: 2, GSM, GPRS, EDGE, UMTS, HSDPA
It seems to think that the network only supports UMTS, but that's surely not the case with T-Mobile US. I've used this sim card before to get HSPA, (as well as HSPA+ and LTE) connections with other devices.
My signal seems decent at -83dBm.
Is there an AT command I'm missing that I can send to enable or force HSDPA?
My concern here is mainly about latency; HSPA has lower latency than UMTS. However, it would also be nice to take advantage of the "DL3.6Mbps HSDPA" supported by the module - I'm only able to get about 500-700kbit/sec downstream.
Thanks in advance for any hints or tips.
